There could be something else useful on your system: the SYSLOG
files.  It sounds like you are running a Gnu/Linux box, so please look
in the SYSLOG files (if you don't know where or how, please read the
relevant man pages first), and try to find any messages related to the
crashed Emacs session.

Also, please make sure your shell setup doesn't disable core dumps
(with a ulimit command).

In general, if Emacs crashes, it should leave behind a core dump file;
if core files are not disabled, then it's possible that Emacs was
either killed by the OS (thus the advice to look in SYSLOG), or it
simply exited.
