Core dumps are automatically enabled.  Your system or user config may
change the maximum core dump size to zero, and that would stop them
getting saved.

The app will dump core in its current working directory, which could
be anywhere if it decided to change it.  I would guess (just a guess)
that the panel stays in you home dir, so if your app does not chdir
then it would still be there too.  Have a look at the "cwd" link in
the process's /proc dir the next time you try.  You should also run it
from bash instead of the panel, and run ulimit -c first to see if your
core file size has been restricted.
