The program will not exit until all threads have completed its
execution.

The program was compiled using C++ compiler v 3.6.4

Whenever I run the program with more than 1 thread, it will always core
dump.   It happens even if the program were to be compiled with
xlC_r7.   However, when I compiled the SAME program on AIX 4.2.1 with
the same compiler, the program runs fine even with 400 threads.

Has any one experience the same kind of problem in AIX 4.3.2 using C++
compiler v3.6.4?

I just found the same problem (little pthread test app could reproduce
it perfectly).
I think there are a bunch of updates for packages (xlC.rte and
ibmcxx.cmp, ibmcxx.lib and ibmcxx.rte) which patch it up to 3.6.6.x
(available at IBM's RS6K page). Although they address
a 'memory leak' problem with threading and exception handling - maybe
they solve this problem as well (maybe its even just _this_ problem).
However some of our 3rd party vendors (like Iona and Rogue Wave), state
to use the 3.6.4 version of the compiler, so Iam not sure wether to just
have a try with the new versions. BTW how did they successfully test
their products? ;-)

Maybe someone can bring some light in this darkness...
