[Samba] panic action on samba 3.2.0 (suite)

Hi,

I have already some panic action.
I added a /bin/sleep 9000 to my script.

I have a bt :

#0 0x00002aaaadfbb0e5 in waitpid () from /lib64/libc.so.6

This is a bug that got fixed in 3.2.2 (mixing up talloc and malloc).
Sorry for the problem.

Jeremy.
