Thank you for telling us about this bug.

I did try to reproduce the bug using the latest version of the 
binutils development sources, but the problem did not occur.
Possibly you are using an older set of sources, or you are
running the test on a machine with a limited amount of stack
space.

Either way, please could you check the problem, and if it
still exists, report it here:

  https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc

This is actually the gcc bug reporting system, since the C++
demangling feature of the xc__filt program is actually supplied
by the libiberty library, which is maintained as part of gcc
rather than binutils.

Cheers
