Re: objdump read_section_stabs
Commit f9c36cc99518 changed (and renamed) read_section_stabs with one
difference in overall behaviour. Previously read_section_stabs would
return a NULL for an empty section, which was then treated the same as
a missing section. Now an empty section is recognized and dumped.
This leads to NULL stabp and stabs_end in print_section_stabs. Since
stabs_end - STABSIZE is then a pointer to a very large address, the
test "stabp < stabs_end - STABSIZE" succeeds.
* objdump.c (print_section_stabs): Correct STABSIZE comparison.
