I generated the core dumps in two ways: via null pointer derefernce in program and via gdb attach and gcore. In both the cases, I am unable to read the core files. Do you have any thoughts? I tried with both gdb 7 and gdb 6.7. For gdb 7, I tried two different machines maintained by different organizations to see what the issue may be. Both are failing. Thanks, --sudhakar
