Hi,

OpenSIPS is dying with "libmysqlclient.so Segmentation Fault" after
MySQL server restart. The log shows
"opensips[16769]: segfault at 4c8 ip 7f36728bf283 sp 7fff7ba11a90
error 4 in libmysqlclient.so.15.0.0[7f3672862000+1bf000]"

and gdb bt shows:

Server runs fine after restart until MySQL is restarted again. In my
lab setup, OpenSIPS is getting killed triggered by registration
request every morning (probably due to MySQL being restarted daily
with logrotate).

The server is the latest trunk on Debian lenny/AMD64.

Thanks,
Om.
