It should have called bfd_assert.

Have a look at bfd_assert in bfd.c. GDB is one of those libbfd
clients that would benefit from calling bfd_set_assert_handler
(recently added, post binutils-2.22) with a handler function to
do longjmp to error recovery of the current command or
something. See ld/ldmain.c for usage.
