Subject: Re:  Segmentation Fault during Code Loading

  All of the code is compiled with -g (and I think -gstabs).

As I said before, the strange thing is, the code will work until I add 
another shared library to the link line even though I don't call any of 
its functions and there are no static constructors in that library.

The reason I am trying with gcc 2.95.3 is that a number of our clients 
have distributions like Redhat 7.3 installed and, as far as I know, gcc 
3 produces code that will not link with the runtime libraries of the 
older distributions. Please correct me if I am wrong.

My other problem with providing an example is that this problem only 
happens when the code is large. I can provide the executable and the 
shared libraries if that would be helpful but the source code is part of 
our development tree and runs to 100,000+ lines of code..

Regards,

Jason
