Hi Jan,
Thank you for your reply and sorry for coming back so late on the
subject. Below is some output from SER and the backtrace that I obtained
with gdb.

Unfortunately the coredump itself is not enough, could you make a
backtrace in gdb so that we can see where exactly does it crash ?

Hi all,
I'm running SER 0.9 on an FEDORA CORE 3 machine and it crashes every
time I try to use mysql module. I have compile SER in mode debug and spent
some time trying to figure it out. I first found a bug in the q_find_free
function in q_malloc.c:290: "if (f->size == size)" which cause memory
access violation when f is NULL. I fixed this but it didn't solve the
problem.
I attached here the coredump and the ser.cfg file. The version of
MySQL
Server and libraries is 4.1
Any helps will be highly appreciated,
Quang
