Alan, to clarify something here.

I know BFD intentionally doesn't use the x*() functions.  Instead it 
tries to clean up and return an error indication when there is a 
malloc() failure.

What of the disassembler though?  GDB, which is depending on the 
disassembler, needs to be able to recover from low memory (aka malloc() 
failure) conditions.  Is using xstrdup() in the disassembler going to 
lead to memory leaks in the case where xmalloc() fails?
