I think this is a misattribution of the failure. #203481 is a change of the CMake build system, it does not change anything functional in the flang compiler. #203481 had a build problem which was fixed in #204438. But since Flang built successfully, it cannot be the problem of that CI problem.

Thank you for your comment. As you pointed out, it appears this commit is not related to the issue. I apologize for the false detection.
As this issue appears to be identical to "https://github.com/llvm/llvm-project/issues/191844," which is currently being investigated by the community, we will close this issue.
Best regards, Yasuyuki Ohno
