There are 2 C++ demanglers, one in libiberty and the other in libstdc++. Unfortunately the one in libiberty doesn't work right with the current gcc: http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7986 The demangler in libstdc++ works correctly. What is the plan to fix the C++ demangler in libiberty? H.J.
