Code to demonstate nptl fault

Comment 2 Jakub Jelinek 2003-04-09 07:08:29 UTC
This ought to be fixed in the proposed glibc bugfix errata.

Comment 3 Ulrich Drepper 2003-04-17 04:08:23 UTC
Try glibc-2.3.2-27.9 and let us know.  The program prints "success" for me.

Comment 4 David Watson 2003-04-17 04:48:02 UTC
Fixed in errata.
