[Dovecot] increased core dumps with v2.2.7

Hi,

After upgrading to v2.2.7 yesterday, I am starting to get a larger number of bugs occurring -- unfortunately I hadn't configured things to save core dumps (now done).

But I am seeing things like:

dovecot: imap(user@example.com): Fatal: master: service(imap): child 27931 killed with signal 11 (core dumped)

kernel: [151706.763475] imap[4878]: segfault at 7fff53b0aff8 ip 00007fdc7ed65ece sp 00007fff53b0b000 error 6 in lib20_zlib_plugin.so[7fdc7ed61000+7000]

dovecot: imap(user2@example.com): Fatal: master: service(imap): child 4870 killed with signal 11 (core dumped)

As soon as I have more info., I'll let you know.
