Hmm, I think this one will need some more investigation.  Do you have
a *small* file that reproduces this problem (rather than the large 3rd
party version) that you could send to me ?  if not, then can you put
the large file somewhere where I can download it via FTP ?  (Assuming
that you are allowed to make this file public).

Cheers

PS.  Is this problem related to the other ieee linking problem that
you posted earlier ("ld 2.13 dumps core/seg faults") ?
