[Bug 45289] New: Wine Crashes Some Programs If Compiled with AVX Support
by wine-bugs＠winehq.org April 3, 2026

https://bugs.winehq.org/show_bug.cgi?id=45289 Bug ID: 45289 Summary: Wine Crashes Some Programs If Compiled with AVX Support Product: Wine Version: 3.9 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: ben(a)xnode.org Distribution: --- This is a really specific bug and I'm not sure what other programs/games it affects. I assume there are more, but this is the only example that I've reliably run into at the moment: == To Recreate Run Cemu under a 64bit Prefix. Start Mario Kart 8. After Mario announces the game, it will crash. == Workaround Compiling Wine without AVX support (i.e. adding the -mno-avx C/XXFLAG) negates the issue. People won't see this when using distro packages because they'll be compiled using something like -march=x86-64 which doesn't enable any of the AVX options (as they aren't available in all processors). If you compile it yourself using something like -march=native then GCC will enable the AVX functions which in turn triggers this issue. I saw this behaviour on both my old i7-5775C and the i7-8700K which has since replaced it. In case it's relevant, it looks like this problem may have not existed before Wine 3.0 because I've tracked down an old post of my own wherein I stated (regarding the Mario Kart 8 crash on Cemu): ======================= Tried on a brand new Wine 3.2 prefix, same issue (Segmentation fault after the splash screen). Works fine with Staging 2.21. More specifically: 002c:fixme:seh:RtlCaptureStackBackTrace (0, 40, 0x25152ba0, (nil)) stub! 002c:err:seh:call_stack_handlers invalid frame 25153728 (0x116a0000-0x117a0000) 002c:err:seh:NtRaiseException Exception frame is not in stack limits => unable to dispatch exception EDIT: The issue was vcrun2015. Wine-staging didn't need it. Standard wine does, for some reason. ======================= Not sure if the vcrun2015 issue was a red-herring as that's installed now but no-longer fixes the issue. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59573] New: Regression introduced by decompression support in winhttp
by WineHQ Bugzilla April 3, 2026

April 3, 2026

http://bugs.winehq.org/show_bug.cgi?id=59573 Bug ID: 59573 Summary: Regression introduced by decompression support in winhttp Product: Wine Version: 11.5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winhttp Assignee: wine-bugs(a)list.winehq.org Reporter: sutupud(a)yahoo.com Distribution: --- Initial problem was voice chat being broken in Overwatch, trying to connect resulted in an error message. I bisected it to 335ae4237c72f09408e9b1b26b1d5f3891ed9a3c On looking more closely through the output of WINEDEBUG=+winhttp, the server response has a "Content-Encoding: utf-8" header. That triggers this branch here: https://gitlab.winehq.org/wine/wine/-/commit/335ae4237c72f09408e9b1b26b1d5f… The query here checks for the wrong header, it should be for WINHTTP_QUERY_CONTENT_TRANSFER_ENCODING, not for WINHTTP_QUERY_CONTENT_ENCODING! Changing it to that fixes the problem. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

Preview of Elster tax calculation in Buhl Tax 2026 (and earlier versions) were working. Starting with wine-staging 11.2 the d2d1 geometry groups were implemented in master. - Now the preview of Elster tax calculation in Buhl tax 2026 is only showing blank pages (again). - Scrolling through the blank pages quickly fills the RAM with several GB, closing the preview window doesn't free the memory This is confirmed also with (non-staging) wine 11.5. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
