Eric Lemings commented on STDCXX-262:
-------------------------------------

This problem is apparently due to a bug in the G++ ABI implementation on Darwin and is supposedly fixed in the GCC 4.2 release series.  Hopefully, Apple will pick this regression fix up in a future release.  (Leopard/Xcode 3.0 maybe?)

See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25908 for more details.
