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
