malloc and threads

Please post the code!

malloc never was reentrant and probably never will be.

If you mean "thread-safe", I'm not aware of any thread-related
problems in malloc, in particular not anything that would cause the
program described above to fail.  That also holds for glicbc-2.2.2,
even though that's _really_ old now.
