[PATCH v2 0/7] MR9027: winegcc: Force subsystem version to 5.2 on both Clang and MinGW.
by Rémi Bernon (＠rbernon) 21 Oct '25

21 Oct '25

This would hopefully fix some comctl32 test failures which started happening after I changed my nightly winetest runs to build Wine with Clang. -- v2: winegcc: Force default subsystem version to MSVC modern values. user32/tests: Force console subsystem version 5.2. quartz/tests: Force console subsystem version 5.2. dxgi/tests: Force console subsystem version 5.2. comctl32/tests: Force console subsystem version 5.2. winegcc: Support subsystem version number in link.exe-style cmdline. winegcc: Consistently use the subsystem option with Clang and MinGW. https://gitlab.winehq.org/wine/wine/-/merge_requests/9027

[PATCH 0/2] MR9215: iphlpapi/tests: Give GetBestRoute2 a SOCKETADDR_INET. (ASan)
by Bernhard Übelacker (＠bernhardu) 21 Oct '25

21 Oct '25

The test also calls GetBestRoute2 with only the smaller sockaddr_in but reads inside the whole SOCKADDR_INET type. Therefore I recived this ASan report, reading 28 bytes from variable with only 16 bytes. The second patch removes a few unneeded casts to SOCKADDR_INET. But there are more which ASan does not complain about here, should they also be changed to a SOCKADDR_INET type?
