[Serusers] qm_malloc problem

[Jan Janak]

Hello, It would be great if you could generate a core dump. Simply use
ulimit -c 1000000 to set higher limits for coredumps and try to restart ser.
It should then write something like segmentation fault, core dumped.

Once you manage to create the core dump, compress the whole ser (including
sources, compiled binaries and the coredump) and send it to me (to
J.Janak at sh.cvut.cz, not on the mailing list).

That would really help and I will try to find out what's wrong. Thanks for
the report.

  Jan.
