From 5dc30b5fba761013c064a9b9de6fc39dc2be01e2 Mon Sep 17 00:00:00 2001 From: Jonas Hahnfeld Date: Wed, 6 Jan 2016 10:10:39 +0400 Subject: [PATCH] GDB SIGSEGV opening a Fortran program compiled with ifort This patch fixes a SIGSEGV when trying to open a Fortran program compiled with ifort (reproduced using version using version 16.0.1.150). The error can be reproduce with most, if not any program. For instance, a single file only containing "end", compiled with no additional flag, suffices. gdb/ChangeLog: PR gdb/19208 * dwarf2read.c (read_partial_die): Do not call set_objfile_main_name if the function has no name. --- gdb/dwarf2read.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gdb/dwarf2read.c b/gdb/dwarf2read.c index c410500..1020c12 100644 --- a/gdb/dwarf2read.c +++ b/gdb/dwarf2read.c @@ -15936,7 +15936,8 @@ read_partial_die (const struct die_reader_specs *reader, compilers pick up the new representation, we'll support this practice. */ if (DW_UNSND (&attr) == DW_CC_program - && cu->language == language_fortran) + && cu->language == language_fortran + && part_die->name != NULL) set_objfile_main_name (objfile, part_die->name, language_fortran); break; case DW_AT_inline: -- 2.5.0
