   I can verify the bug with today's cvs. Here is the patch.

Thanks.  I wonder why I didn't see the problem.

Please try the appended patch instead.  That tests the actual
characteristic we are interested in, rather than testing something
else and potentially covering up a different bug.

Incidentally, Mark, that code ought to be checking that the input file
is an ELF file before it calls elf_section_data.
