Free-threaded builds with PGO fail to build on Windows #123153
Description
Bug report
Bug description:
I don't consider this a high-priority bug, since free threading remains experimental, however it does prevent us from getting accurate benchmarking figures for free-threaded builds on Windows.
Building with
PCbuild\build.bat --pgo --disable-gil -c Release
currently fails with an internal compiler error:
C:\actions-runner\_work\benchmarking\benchmarking\cpython\Python\ceval.c(761): fatal error C1001: Internal compiler error. [C:\actions-runner\_work\benchmarking\benchmarking\cpython\PCbuild\pythoncore.vcxproj]
(compiler file 'D:\a\_work\1\s\src\vctools\Compiler\Utc\src\p2\main.c', line 224)
To work around this problem, try simplifying or changing the program near the locations listed above.

Given that it's an
Internal compiler error, maybe worth reporting the bug to Visual Studio?mdboom commentedon Aug 19, 2024
Sorry, I should have said so, but I plan to.
