I've compiled a program in Linux that I'd like to profile, using -pg
with gcc. (I'd like to be able to view some profiling data with gprof.)
When I run the program, I get an error at the point the program is doing
a "select" to get a packet from one of the ethernet interfaces. The
strange thing is that the program can send and receive some ARPs before
this error occurs. Has anyone seen anything like this before?

Also, are there other profiling tools (preferrably freeware) available?
I basically want to be able to see where the potential bottlenecks in
the program are.
