[Bug ld/6511] New: segmentation fault building final object

From: frediano dot ziglio at vodafone dot com
Subject: [Bug ld/6511] New: segmentation fault building final object
Date: 13 May 2008 12:31:19 -0000

I built a cross compiler for an hp-ux 11.00 (quite old, I know).
Build command is

../src/binutils-2.18/configure --host=i386-linux --build=i386-linux
--prefix=$HOME/parisc-linux/parisc --target=hppa64-hp-hpux11.00 --disable-nls
make install

during linking I got

$ bt
Program terminated with signal 11, Segmentation fault.

0x08082fa3 <elf64_hppa_finalize_opd+243>:       add    $0x82,%eax

so I think bfd_link_hash_lookup returned NULL ...

Tell me if you need other informations.
