------- Comment #1 from paolo dot carlini at oracle dot com  2010-01-09 10:19 -------
c++filt is part of binutils and indeed the PR is about binutils, thus doesn't
belong here. If you have strong reasons to believe GCC is at fault, please
explain and reopen.

_GLOBAL__I__Z2fnv
global constructors keyed to _Z2fnv

Shouldn't it be

c++filt is part of the binutils, but it just runs the demangler which is part
of gcc.  Any change here will be a change to the demangler.
