Bug Description

Binary package hint: gdb

BFD chokes on the .gnu.hash sections. This is a duplicate of #73724, but even though the original is flagged as fixed it is still broken on x86_64.

  return 0;

Hi there
Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the development branch of Ubuntu, Hardy Heron?

Thanks in advance.

 I've given up and switched to the 32-bit version so I can't check if
things work or not. If I recall correctly, the i686 version of gdb
(bfd?) had been patched but not the x86_64 version.

Can someone confirm if this is fixed in the x86_64 version of Hardy?
