It seems to be an incompatibility issue between the NPTL and gcc-2.95.x:
http://sources.redhat.com/ml/glibc-bugs/2004-06/msg00144.html

The best way to solve this would be to get rid of the MT support for building 
the GCC-based instrumenter, since we don't need it, and libio/ compilation would 
not break. I'll look at some way to fix this.
