I can't reproduce this with the current development version of glibc
2.1 (2.0.95 plus lot's of patches).  I see the following explanations:
- you're linking against an old version of libpthread (check you link
  command line with e.g. gcc -Wl,--verbose)
- this has been fixed already
- some kind of compiler error

Can anybody else reproduce this?
