Can someone please help me identify the cause of the 
problem. Is this really a compiler error as mentioned 
above.

thanks,

I have a very similar problem under SuSE 8.1 (gcc3.2)
Also an Internal compiler error in cregex.cpp.
But my gcc3.2 is completely different from your gcc2.96.85.
Please let me know if you have found anything out.

Yes, it is a compiler bug - upgrading to gcc 3.3 will fix the 
issue.  If you have a patch that fixes the problem for 2.96 
then I will apply it, but I'm not going to spend time looking for 
one given that this is a non-official gcc release.
