gdb shows this caused by a call to ieee_write_expression() in 
bfd/ieee.c:2496 (binutils 2.13) with a NULL pointer in 3rd parameter 
(pointer to asymbol). The null pointer is shortly de-referenced inside 
the function causing segfault. Don't see a difference in latest cvs. 
Don't know all that is going on but perhaps should just return false 
instead of calling ieee_write_expression() when r->sym_ptr_ptr is null 
at li 2486?
