Bug ID: 17597
Summary: NULL pointer dereference in opncls.c in
bfd_get_debug_link_info().
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: oxffffaa at gmail dot com
I use tcc to compile simple source, but when i try to 'objdump -S -d a.out' it
crushes with SIGSEGV. Reason is in opncls.c, function 'bfd_get_debug_link_info'
in line: 'crc_offset = strlen(name) + 1;' because pointer name is NULL and
strlen requries valid pointer. So is it problem of tcc(i mean this pointer
can't be NULL) or problem of bfd? I add check for whether name is NULL or not
and objdump seems work with this case.
