/opt/gcc/work/gcc/testsuite/gfortran.dg/debug/pr35154-dwarf2.f -g3
-gno-strict-dwarf
/opt/gcc/work/gcc/testsuite/gfortran.dg/debug/pr35154-dwarf2.f:14:0: internal
compiler error: in darwin_asm_output_dwarf_offset, at config/darwin.c:2706

sense on darwin? I thought that darwin is a "strict-dwarf" target.
