libbfd crashes when linking in elf_i386_relocate_section

Hi all!

A month ago I already posted this error to gnu.utils.bug, but apparently
the list is not working currently (I wrote a follow-up today, but it did
not appear in the newsgroup).

The problem is that the linker crashes when linking an own application with

/usr/bin/ld: BFD 2.14.90.0.7 20031029 Debian GNU/Linux internal error,
aborting at ../../bfd/elf32-i386.c line 2247 in elf_i386_relocate_section

I already tried binutils 2.15 which I built from the original tarball,
but the error remained.

This problem suddently appeared; I did not make any changes to the code
which was building correctly for years. I did some debugging and found
out that the linker crashes as soon as two of three "critical" objects
are linked together.

The abort() is called in the following lines:

if (off >= (bfd_vma) -2)
~            abort ();

I added some tracing code and figured out that it is indeed caused by
one of the "critical" object files with section *UND*.

If there is more that I can do in order to locate the problem, it would
be great if you could let me know. I am a little lost and don't know if
I am trying to figure things out in the right direction.

Thanks a lot,

	Fabian

Please open a bugzilla bug report and provide a small testcase.
