Hi Thomas, since about 2 months typebound_call_22.f03 is failing on the GCC-8 and GCC-9 branches: XPASS: gfortran.dg/typebound_call_22.f03 -O scan-tree-dump-times optimized "base \\(\\);" 1 This is related to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91984#c2, most probably. Could you look into this? Thanks, Manfred
