nm -l crashes because of a NULL pointer deref in dwarf2.c. functionname_ptr can be NULL and there are tests in the logic of the function find_line to deal with that case. Yet, in line 2383 of current top, functionname_ptr is dereference without check for NULL.
The fix is to check for NULL before using functionname_ptr. I tried a one-line fix and it seems to work. -- Summary: SEGV fault due to NULL pointer deref in dwarf2.c Product: binutils Version: 2.18 (HEAD) Status: NEW Severity: normal Priority: P2 Component: binutils AssignedTo: unassigned at sources dot redhat dot com ReportedBy: dougkwan at google dot com CC: bug-binutils at gnu dot org GCC build triplet: i686-linux-gnu GCC host triplet: i686-linux-gnu GCC target triplet: i686-linux-gnu http://sourceware.org/bugzilla/show_bug.cgi?id=4797 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
