Hi,
I'm using elog 313 on an ubuntu server.

Additional information: I tried to recompile with -g (debug) and run it in gdb but the crash is not reproduced that way (w/ or w/o gdb). I guess that the
memory handling in debug mode is different so the corruption is not
there anymore.

Can you try to reproduce it on this (!) server? I cannot reproduce it on my home copy server, so I guess that might be fixed in meantime. Can you update
to the current version of elog?

I found two potential memory leaks which I fixed in the git version, so you can try again.
