[PATCH 0/1] MR9716: mf: Don't crash if stream is null during sample request.
by Charlotte Pabst (＠CharlottePabst) Dec. 12, 2025

Dec. 12, 2025

JR East Train Simulator's sink sometimes requests a sample before the stream is added. This would then lead to a crash. If no stream is present, buffer sample requests until a stream is added (This is necessary to prevent swallowing requests). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9716

[PATCH v9 0/4] MR9265: crt: Run MSVC constructors and destructors
by Yuxuan Shui (＠yshui) Dec. 12, 2025

Dec. 12, 2025

There are several motivations to enable ctor/dtor support: 1. ASan. This is not just about my wine-asan work, this is important for @bernhardu's PE asan work as well. The compiler generates ctors that poisons memory around global variables so misuses of them can be caught. This is the same both of our implementations of ASan. 2. Building third-party codebases against wine's CRT. This is not necessary for mingw-gcc or llvm-mingw, but the MSVC frontend of clang is another option for cross-compiling to Windows. However right now that requires Windows SDK. Bringing wine CRT to the point of being functional enough will give us another option. Could be useful for things like Proton. 3. (Controversial) Many dlls perform init/deinit tasks in `DllMain`. Some of them might benefit from a conversion to ctor/dtor. Since nothing in wine uses ctor/dtor right now, this change shouldn't have any impact by itself. -- v9: crt: Run MSVC constructors and destructors. winecrtend: New staticlib hosting fallbacks of initterm and initterm_e. https://gitlab.winehq.org/wine/wine/-/merge_requests/9265

That sounds odd, that it would crash specifically dependent on the function name. Is the crash specifically only with Clang == 20, or for newer/older versions too? Can you give more details about the build configuration - building `except.c` as COFF, for x86_64? With the compiler invoked in MSVC mode (which is the default in Wine today) or mingw mode? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9762#note_125552
