--- Comment #12 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-12-19 18:41:24 UTC --- (In reply to comment #9) > subroutine foo > BLOCK_NAME: block > end block BLOCK_NAME > end subroutine foo > subroutine BLOCK_NAME() > end subroutine BLOCK_NAME The problem is the call to "gfc_fixup_sibling_symbols" which finds in "subroutine foo" the symbol "block_name" (FL_LABEL) - and overrides it with the subroutine (FL_PROCEDURE). The source code has: > /* By 14.6.1.3, host association should be excluded > for the following. */ I think it missed F95's "(13) The name of a named construct" Patch: --- a/gcc/fortran/parse.c +++ b/gcc/fortran/parse.c @@ -3908,6 +3908,7 @@ gfc_fixup_sibling_symbols (gfc_symbol *sym, gfc_namespace *siblings) || old_sym->attr.intrinsic || old_sym->attr.generic || old_sym->attr.flavor == FL_NAMELIST + || old_sym->attr.flavor == FL_LABEL || old_sym->attr.proc == PROC_ST_FUNCTION)) { /* Replace it with the symbol from the parent namespace. */
