core file not created

[Katherine Meiszer]

I am running code compiled with g++ using gcc version egcs-2.91.66 on a 
Linux system.  When I get a segmentation fault, no core file is 
created.  I have never before seen an instance of where a segmentation 
fault is not accompanied by a core dump.  I wrote a simple test program 
that does nothing but incorrectly index an array and it also does create 
a core file when it crashes.

I would appreciate any suggestions you have on how to fix this.  It's 
making debugging very difficult.

Thank you,
