28.9.0.2 crashes on some sites Topic is solved

[tsifra]

Hi! I've created issue on github and got directions to post here.

New version 28.9.0.2 often crashes on some sites. If i browse facebook crash is almost guaranteed. Problem was noticed on 28.9.0.1. Prev version was okay as i remember 28.9.0. Program was initially installed from ppa. So i can't find a way to downgraderight now.

Yesterday i've tried to complie 28.9.0 from source but it's unstable. Please help to investigate and collect needed details.

PS: it's veryhard to post on this forum from Russia. We have to use vpn here to get to frre internet, but some vpn servers are blocked by forum. So have to switch off vpn etc.

Try running in safe mode and see what happens.
Also please post the required troubleshooting informations as indicated in the stickied threads.

[tsifra]

Safemode also crashes with message "core dump", but in my opinion it's much more stable than normal mode.

How to reproduce.
1. Reboot machine
2. Load Palemoon
3. Goto facebook.com
4. Scroll page
5. Find post with "Read more" and click link to open new tab OR open any post in new tab by right-click on date mark
6. IfPalemoon doesn't crash repeat 4-5 several times

Tech details:
Your Operating system - ubuntu 18.04 64 bit
The exact version of Pale Moon you are using (desktop/portable. 32/64 bits, exact version number) - desktop 28.9.0.2
Basic hardware information if relevant: CPU, graphics card, amount of RAM - AMD Ryzen 3700X, RX580 graphics, 32Gb RAM
A description of the problem - crash while browsing
Bugzilla bug number if found - not found
Steps to reproduce the problem - described upper
Expected result - not relevant
Actual result - not relevant

Please include the information in Help -> troubleshooting information (copy text)
More details about the crash would also be helpful.

[tsifra]

Menu "Help -> troubleshooting information" causes Palemoon crash also. Don't know how to give more details on this issue. Maybe i can run some debugger or something to collect data?

That's not something that should happen.
Can you list your extensions, at least?

[Moonchild]

If you are using Steve Pusser's repositories, please try updating to the +repack one recently updated there. There have been issues with some of the binaries put out by him lately using the wrong /mismatched source code.

[tsifra]

I'm on compiled from source version right now. Git cloned on 01 apr. All extensions were switched off, but not uninstalled. Should i try to uninstall them?

I have
Tab Mix Plus
ABPrime
nMatrix

But all extensions are switched off. Problem appeared in 28.9.0.1 first several days ago. I tried to compile earlier version. But result is the same.

What branch? if it's anything but a tagged release, then you should rebuild from a release tag.

[tsifra]

I followed instructions here https://developer.palemoon.org/build/linux/

So initial command was
git clone https://github.com/MoonchildProductions/Pale-Moon.git ./
and then step-by-step
..
cd ..obj..
sudo make install

Is it latest release? I've fetched new sources right now and compiled again. Help ->Troubleshooting still causes crash. As i mentioned in starting message I had to compile from source only after 28.9.0.2 update was also unstable. I was using Steve Pusser's repositories before.

[Moonchild]

Is it latest release?

If you followed the instructions there step by step (git first, then going to Build Instructions and carefully following he steps there) then it's pretty much release (+1 unreleased commit)
But:

sudo make install

Nowhere does it say you should do this.

Are you sure you followed the instructions completely?

Also, have you considered running the pre-built and tested binaries instead of puttering around with compiling from source?

P.S.: For obvious reasons our support for people building from source and running into stability issues with their result is very limited, especially on Linux where there are too many variables influencing build time and run time.

[tsifra]

You're right. Running "sudo make install" was very bad idea. There is no "make uninstall" etc Have to deal with it before providing any new details. Will try PPA again after all.

UPD: Succeeded with manual uninstalling. And installed PPA version from stevenpusser. Symptoms are the same. Crash when calling for troubleshooting menu. Have to wait for the next version i guess. But please consider that 28.9 was brilliant.

And installed PPA version from stevenpusser.

(as in, from the Pale Moon website)

Have to wait for the next version i guess.

... We can't fix what we don't know is broken. If it is actually a bug in the browser then it'll have to be fixed -- it won't magically "solve itself".

[tsifra]

Sorry for my misunderstanding.
I've tried two versions today. One from PPA another one was downloaded here http://linux.palemoon.org/download/mainline/
Both were unstable. Simplest way for testing now is calling troubleshoot menu that guarantees crash every time.

I've installed exactly the same system on virtualbox machine and browser was stable. So there is some problem exactly with my host machine. Maybe there are some bugs in code, but i think it would be very hard to debug.But we can try, if there is a way.
Thanks for your help and great browser, Moonchild

UPD: Transfered my profile to virtualbox machine. The same result. Browser is stable. So i suppose it's completely because of my machine.

[Moonchild]

Without more crash details (exception code, crashing module, etc. etc.) it's hard to say but this looks like this might be a graphics driver issue. The troubleshooting page does a few tests/graphics calls to gather information about graphics capabilities and it's possible that a broken driver crashes the browser when it is probed this way (e.g. for WebGL). That would not occur in a virtual machine because of the hardware virtualization.

[tsifra]

You're right! I've uninstalled my amdgpu 19.50 (latest available) driver and everything is stable now. There was one more program affected, it was VLC video player.
Driver was not upgraded for a long time. Looks like some package that was upgraded the same day as 28.9.0.1 was released broke some amd driver functions.
Thanks for investigation and hints. Have to stay some time on generic linux drivers.
