Title:
Clang 22.1.7 crashes during C++23 module compilation (internal compiler error)
Description:
Clang crashes when compiling a C++23 module in an MSYS2 UCRT64 environment. The error is reproducible. The error occurs when attempting to include a class file with the () operator with a large number of specializations.
Environment:
clang++ 22.1.7
Target: x86_64-w64-windows-gnu
MSYS2 UCRT64
Windows 10/11
Command line:
C:\msys64\ucrt64\bin\clang++.exe -DFMT_SHARED -DFile_EXPORTS -D_WIN32 -D_WINDOWS -ID:/Luna/root/file/include -ID:/Luna/root/external/fmt/include -ID:/Luna/root/common/include -stdlib=libc++ -ggdb -std=gnu++23 -fms-extensions -Winvalid-specialization -MD -MT root/file/CMakeFiles/File.dir/module/serialize/json.cppm.obj -MF root\file\CMakeFiles\File.dir\module\serialize\json.cppm.obj.d @root\file\CMakeFiles\File.dir\module\serialize\json.cppm.obj.modmap -o root/file/CMakeFiles/File.dir/module/serialize/json.cppm.obj -c D:/Luna/root/file/module/serialize/json.cppm
