Re: Program execution

[Markus Rechberger <mrechberger@gmail.com>]

Hello,

first enable coredumps
# ulimit -c unlimited
# ./yourfaultyapp

open another shell and kill the process using kill -SIGSEGV then it
should say core dumped (also compile your application with -g .. there
are a few other debugging options but that one might already help you)

afterwards run your application with gdb (should look like the following line)

# gdb ./yourfaultyapp coredumpfile
> bt // for a backtrace, last functions which got called and so
> frame #<framenumber> // inspect a frame
> list // show the sourcecode which is connected to that frame

hope this helps,
Markus
