--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- I don't see the ICE on a standard GCC11, but its instrumented version gives ../../work/gcc/fortran/simplify.c:127:10: runtime error: load of value 4294967295, which is not a valid value for type 'expr_t' ../../work/gcc/fortran/error.c:970:2: runtime error: member access within misaligned address 0x000000000002 for type 'struct gfc_linebuf', which requires 8 byte alignment 0x000000000002: note: pointer points here <memory cannot be printed> ../../work/gcc/fortran/error.c:971:46: runtime error: member access within misaligned address 0x000000000002 for type 'struct gfc_linebuf', which requires 8 byte alignment 0x000000000002: note: pointer points here <memory cannot be printed> ../../work/gcc/fortran/error.c:979:42: runtime error: member access within misaligned address 0x000000000002 for type 'struct gfc_linebuf', which requires 8 byte alignment 0x000000000002: note: pointer points here The instrumented GCC9 and 10 give the expected error.
