    The linaro reported an issue in https://linaro.atlassian.net/browse/LLVM-1528 where [this file](https://github.com/fujitsu/compiler-test-suite/blob/main/Fortran/0394/0394_0031.f90) from the fujitso testsuite will fail to compile after PR#122770. I looked at it and it seems that compiler is not crashing or stuck. The file has a lot of cyclic derived types and it is taking long time to finish with -g. The code is quite contrived but the compilation time should be reduced.
