That's two and a half bugs in my code: * flags = 0 passed to LockBits(), undocumented behavior is that method succeeds and at least writing to the buffer works. Looks like 0 needs to be treated as ImageLockModeRead|ImageLockModeWrite? * Wrong error handler used, unintended treatment of Gdiplus::Status as HRESULT. * ... and uninitialized bitmapData making above one worse. And finally, looks like exposed compatibility problem is Gdiplus not WindowsCodecs. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59333] VNyan leaks memory (race in __wine_syscall_dispatcher $rsp switching breaks Unity GC)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59333 --- Comment #16 from Hoshino Lina <lina(a)lina.yt> --- My understanding is IL2CPP still uses the Mono runtime and bdwgc (it just replaces the managed bytecode with native code) but I could be wrong about how all the pieces fit together in different configurations. See this random IL2CPP build tree I found: https://git.noc.ruhr-uni-bochum.de/krekem24/ANN_Visualisation_in_AR_Builds/… It's not just any Unity app though, it's specifically Unity apps that use managed threads that perform system calls, and it's a tight race that triggers it. uOSC (what VNyan uses) has a managed thread with a blatant poll loop. It's likely other managed libraries also cause the issue. VRChat doesn't use that though, it uses this: https://github.com/stella3d/OscCore While it does use a receive thread, it uses blocking reads, which means the bug can only trigger *each time an OSC message is received*. If you don't use OSC or use it sparingly chances are ~zero. Meanwhile uOSC: https://github.com/hecomi/uOSC/blob/3c80df7ee3ce7c58cb33f5820921a3b192e22c0… ... polls 1000 times per second, no matter what. So I think this still affects ~every Unity app that uses threads, IL2CPP or not. It's just that the race is so tight, that you're only likely to hit it if the Unity app does Very Silly Things Indeed, like uOSC does. To put things into perspective: If you do use OSC with VRChat but only get messages once per frame at ~60Hz, then you're 16 times less likely to hit the bug than on VTube Studio. If it takes 5 hours to hit the bug on average on VTS, it would take 80 hours on average to hit the bug on VRChat. It's all probabilistic, you can still get unlucky and hit it in 5 minutes, but you get the idea. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

But the EH objects interprets this as HRESULT. And the "FAILED(hr)" may just interpret negative values as errors. Therefore bitmapData seems to contain uninitialized data, and if we are lucky we use the "bitmapData.Stride <= 0" path and get the error message, if we have no luck we enter the path into CopyPixels. Therefore WINEDEBUG=+wincodecs,+gdiplus may be helpful from here. Relaxing the flags check and accepting a flags==0 in GdipBitmapLockBits seems to make the repro to succeed: dlls/gdiplus/image.c @@ -1127,3 +1127,3 @@ GpStatus WINGDIPAPI GdipBitmapLockBits... if(rect->X < 0 || rect->Y < 0 || (rect->X + rect->Width > bitmap->width) || - (rect->Y + rect->Height > bitmap->height) || !flags) + (rect->Y + rect->Height > bitmap->height) /*|| !flags*/) { Can you confirm this? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
