PR pretty-print/67567 do not pass NULL as a string
Fortran passes NULL where a non-null string is expected by the pretty-printer, which causes a sanitizer warning. This could have been found earlier by using gcc_checking_assert. Even if the assertion is false, the result is just an incomplete diagnostic, thus it seems more user-friendly to assert only when checking. I do not have any idea how to properly fix the Fortran bug, thus this patch simply works-around it. gcc/fortran/ChangeLog: 2015-09-25 Manuel López-Ibáñez <manu@gcc.gnu.org> PR pretty-print/67567 * resolve.c (resolve_fl_procedure): Work-around when iface->module == NULL. gcc/ChangeLog: 2015-09-25 Manuel López-Ibáñez <manu@gcc.gnu.org> PR pretty-print/67567 * pretty-print.c (pp_string): Add gcc_checking_assert. * pretty-print.h (output_buffer_append_r): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@228131 138bc75d-0d04-0410-961f-82ee72b054a4
