[Dovecot] CRASH with squirrelmail.

[St0rM]

I'm using:

[root at gwydion root]# rpm -q squirrelmail dovecot
squirrelmail-1.4.3-0.f1.1
dovecot-0.99.12-2.1.fc1.rf
[root at gwydion root]#

It works very good (a bit slow I would say, but ok)...

until I enable MySQL auth mechanism. When I do that, dovecot-auth crashes when squirrelmail try to login. I keep getting:

Jan  7 01:28:31 gwydion dovecot: child 22782 (auth) killed with signal 11

Also, i often get a "stuck" dovecot-auth in R state, looping in a malloc() (if needed I should have a backtrace).

This is the bt:

Is there an easy way to enable -g2 in the Makefile, using configure script?

Thanks.
