v2.2.27 Panic: file rfc822-parser.h: line 23 (rfc822_parser_deinit): assertion failed: (ctx->data <= ctx->end)

Hi,

I've been having an issue with the indexer giving me errors on mailbox
in dovecot.

I managed to narrow it down to a specific email in that mailbox.

Various dovecot functions have issues with this email.

The email itself is just spam. I can email it to you if you want to
analyse it. I did run it through mbox-anonymize but its not clear to me
that that would be of any use. Happy to email the suspect email
privately to anyone who wants it.

/home is mounted nfs4 and is zfs on the nfs server.


Dovecot is installed from Debian Jessie.

Can you install dovecot-dbg and try gdb again?

v2.2.27 Panic: file rfc822-parser.h: line 23 (rfc822_parser_deinit): assertion failed: (ctx->data <= ctx->end)

After some investigation, it turns out it is non trivial to install
dovecot-dbg on debian jessie.

Sorry I can't investigate further.
