We have freeBSD  running on a
We are able to successfully compile and load plugins for RealServer 7.02
using gcc version 2.7.2.1.
However plugins - which are of course nothing but shared libraries (^_^) -
compiled with gcc 2.95.2 are not loaded successfully by RealServer and in
fact RealServer stops responding

What are the possible issues that can be causing this?

Thanks for your time,
Girish

P.S. here's a my makefile for a sample dll which exhibits the same problem
