[Dovecot] imap segfaults in dovecot 1.2 on logout

[Sascha Wilde]

Hi Timo,

when logging out like

a001 logout

the imap child dies from signal 11.  The back trace looks like this:

Program received signal SIGSEGV, Segmentation fault.
0xb7ed4991 in strcasecmp () from /lib/tls/i686/cmov/libc.so.6
(gdb) bt
#0  0xb7ed4991 in strcasecmp () from /lib/tls/i686/cmov/libc.so.6

83                      if (strcasecmp(cmd[i].name, name) == 0) {
(gdb) p cmd[i]
$1 = {name = 0xb7e65ce7 <Address 0xb7e65ce7 out of bounds>, func = 0xb7e6432d, flags = 0}
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

For some reasons this does _not_ happen when I simply close the
connection (without explicitly logging out)...

cheers
sascha
