I tracked it down a bit further. Compiled Exim 4.82 with -ggdb and
enabled core dumps
Just for the records: about "ulimit -c" I knew, but I learned, that
core dumps are still supressed because the binary is setuid,
fs.suid_dumpable had to be set to 1 (valid for Linux).
Here is the stack backtrace...
May be somebody who is more comfortable with this part of Exim may jump in :)
