Synopsis: implementation is not thread-safe on multi-processor machines

Responsible-Changed-When: Tue Jan 15 17:36:08 2002
Responsible-Changed-Why:
    Mine.
State-Changed-From-To: open->closed
State-Changed-By: ljrittle
State-Changed-When: Tue Jan 15 17:36:08 2002
State-Changed-Why:
    Duplicate of libstdc++/5037 (which is closed since it is
    fixed on mainline for 3.1 and, if ever released, 3.0.4+).
    I have tested this case against a patched copy of gcc
    3.0.3 on an MP sparc and it works without crashing.
    I have attached the patch against gcc-3.0.3.
