[Dovecot] 2.1.10 crashes at login (buf->used <= buf->alloc)

[interfaSys sàrl]

Hello,

There is a big problem with 2.1.10.

Here is what I saw in the logs:
Sep 18 22:22:23 imap(): Panic: file buffer.c: line 86
(buffer_check_limits): assertion failed: (buf->used <= buf->alloc)
Sep 18 22:22:23 imap(): Fatal: master: service(imap): child 26833 killed
with signal 6 (core dumped)

Reverting to 2.1.9 with the exact same config file works just fine

Cheers,

Olivier
