Checking the source code of binutils-2.14.90.0.7 I find in bfd/libbfd.c
 
bfd_vma
bfd_getl32 (const bfd_byte *addr)
{
  unsigned long v;

  v = (unsigned long) addr[0];
  v |= (unsigned long) addr[1] << 8;
  v |= (unsigned long) addr[2] << 16;
  v |= (unsigned long) addr[3] << 24;
  return v;
}

My first guess is that addr is NULL.

I tried building binutils-2.15.92.0.2 and found a similar problem.  An exercise
I will repeat here in hopes that it provides additional information.

If additional information would be useful to resolve this problem, please don't
