--- Comment #3 from Patrick Bégou <patrick.be...@univ-grenoble-alpes.fr> --- Following Harald Anlauf idea, I have built the compilers from the devel/omp/gcc-12 branch for testing: GNU Fortran (GCC) 12.2.1 20230302 [OG12] The "internal error" shown with this small test case (begou.f90) do not occur with this branch. I have to test with the full application but I need first to rebuild all the prerequisites (Gcc13 modules files are not backward compatibles with Gcc12).
