------- Comment #2 from burnus at gcc dot gnu dot org 2007-09-10 16:00 ------- Back to fortran; I was wrong. This is not a regression, but it occurred from the beginning as valgrind shows. That it crashes is new, however.
More debugging; the line: common /b/x/c/ ! { dg-error "Syntax error" } is matched properly in gfc_match_common: sym->name is "x" and the typespec looks ok as well. However, in resolve_common_blocks: for (csym = common_root->n.common->head; csym; csym = csym->common_next) { (gdb) p csym $36 = (gfc_symbol *) 0xf475b0 (gdb) p sym->name Cannot access memory at address 0x0 (gdb) p sym->ts Cannot access memory at address 0x20 Thus something corrupts the symbol in between. -- burnus at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Component|middle-end |fortran http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33375
