32bit Pale Moon 34 out of memory when using bing.com translator

[q160765803]

32bit Pale Moon 34's memory usage goes very high and sometimes crashes when using https://www.bing.com/translator

I suspect https://repo.palemoon.org/MoonchildProd ... ssues/2895 causing this problem.

I tested this and do not see any out of order memory usage in Microsoft's translator in 32-bit 34.0.0 release binaries.
I'm also not sure why a translator would make extensive use of a random number generator to the point of causing resource issues...

Can you provide an about:memory dump of your system displaying the problem, and can you also include your troubleshooting information so we can see what environment you are working in?

It shows "heap-unclassified" in a very large value.

The PRNG does not touch the heap. It makes no sense that this change would cause heap memory to inflate.
Please include an about:memory report (measure and save)

I did included it in "hide" section.
And for the heap memory, I wonder if 32bit is allocating too many JIT VM registers that makes javascript engine to allocate more memory?

[Moonchild]

Ah sorry I missed the inclusion. (unfortunately it doesn't really give any pointers)

In the meantime I've been using a debugger because I was able to intermittently reproduce it if I set the target language to Chinese. There seems to be a lot of memory allocation in mozilla::gfx::CreatePartialBitmapForSurface, which makes me wonder if it's one of the [gfx] DiD patches I ported from Mozilla not playing nice with what we have, since that landed really close in time to the PRNG patches. So maybe 84d42d8177aaa17b3dbba0f6fbf33fb3b64870af or 9b52703451069f461e40752e53159149ba8e7c8f + 195251fc127c1b79cab8585080ffea3d959d398b. Maybe you can help check these?
Closing the tab releases all of it cleanly, by the looks of it, which wouldn't necessarily be the case if it was a JIT issue.

I suspect JS one because it seems that it doesn't happen in 64bit Pale Moon and when I tried to make own build to debug it when it starts allocating more memory and it breaks in js::BacktrackingAllocator.
And if I locally backing out JS PRNG changes, memory usage becomes normal.

[Moonchild]

Once again it doesn't seem to make any logical sense for it to touch the heap at all...
And it doesn't explain at all why I see these memory allocations coming from the gfx subsystem clear as day - there isn't anything in the stack touching the JS in the memory hungry call-chains.

[Moonchild]

OK. disabling JIT avoids the memory inflation so it really has to be something with the JIT implementation then.
Maybe I can rewrite it to use fewer registers... that's gonna be a puzzle... otherwise I have to revert to XorShift128+ for 32-bit builds. I'd rather avoid that because it would make for less consistent behaviour across architectures...
