That was less than an hour ago. Does the CI run on a merge branch? Or does that need a rebase?

That was part of a larger project. The error now occurs when attempting to build the following function:
https://github.com/ElmerCSC/elmerfem/blob/66cdc3ea3241a59e927e9b91496856272313c6d1/fem/src/H1Basis.F90#L495-L515

That part of the file hasn't changed in over five years. Same for the header that sets these macros:
https://github.com/ElmerCSC/elmerfem/blob/66cdc3ea3241a59e927e9b91496856272313c6d1/fem/config.h.cmake#L100-L122

It still built and ran the tests about four months ago. See: https://github.com/ElmerCSC/elmerfem/pull/753#issuecomment-4656775888
That was still with LLVM Flang 22. The build logs are probably no longer available.

In the meantime, MSYS2 updated to LLVM Flang 23.1.3. With that, the file no longer built.
And even after backporting the change from here on top of the LLVM 23.1.3 tarball and rebuilding Flang in MSYS2, the file no longer builds. (Now with the error from the previous comment.)
