segfault before main() is called

[Jason . Majors]

I'm trying to use the TCPSession and TCPSocket classes for a threaded 
daemon I'm writing. To test the code in the daemon, I wrote a main that 
bypasses the networking classes (and all cc++ include headers). When I try 
to run it, I get a segfault, before it even reaches the first line of 
main, which is a cout. I loaded it in gdb to trace the execution, but I'm 
not sure how to interpret the output, since it seems to be all library 
code. Can somebody with more knowledge of the libraray tell me what this 
means? 
Thanks.

I'm using gcc 3.3 on AIX 4.3.3 with common cpp 1.1.0.

This GDB was configured as "powerpc-ibm-aix4.3.2.0"...
Core was generated by `jist_test'.
Program terminated with signal 11, Segmentation fault.
