   Thanks for this information. BTW, have you mentioned this in your first
   bug report? I think this patch fixes the bug. 

   Ian, this bug happens on ELF/Alpha when you strip more than one shared
   libraries at a time. It is not the first bfd_zalloc/bfd_alloc bug in
   bfd. It is quite annoying.

This bug was reported on bug-gnu-utils.  I believe I have already
fixed this problem with the appended patch.

We've disagreed before on whether memory should be cleared when it is
allocated, and I think we will continue to disagree.  This was a bug
introduced with a change to the function a few months ago.  The fix is
to avoid introducing bugs; clearing memory is just treating the
symptom.

Ian
