Hi,
etherload is crashing with a segmentation fault, no core file.
RedHat 6.2, SNIPS v1.1.
Someone reported this back in Oct 2001, but I didn't see a
reply to the report. I put some additional debugging print
statements in the etherload.c, main.c and linux.c (see the
typescript below) to identify exactly where it's dying.
As near as I can tell, it dies when it returns from getpkt().
But I have debugging statements immediately before the
return() statement and immediately after the getpkt() call.
I'm stuck. Help?
Thanks,
Darin
