This is going to be difficult to track, then.

You could also build procmail with debugging symbols and use ulimit so that
it creates a core dump. The procedure for the first thing is quite simple:

apt-get source procmail
cd procmail-3.22
export DEB_BUILD_OPTIONS=noopt,nostrip
debian/rules build
fakeroot debian/rules binary
sudo dpkg -i procmail*.deb

Assuming you get a core dump, gdb could then give us some clue of
what's really happening.
