It's quite appropriate.  We appreciate hearing about any bugs that you
find.  (Thanks.)

I think that this problem has been fixed by the following change in the
latest development sources...

        * rs6000-nat.c (xcoff_relocate_symtab): Grow buffer if ptrace()
          fails due to lack of space.

BTW, you can download and build the latest development sources.  See for more information.
