Hi,

one of my mailboxes returns following error when I run doveadm index on it:

Panic: file charset-iconv.c: line 85 (charset_to_utf8_try): assertion failed: (srcleft<= CHARSET_MAX_PENDING_BUF_SIZE)

OS: FreeBSD 10.2 Dovecot: 2.1.19 Tika: 1.10 SOLR: 5.3.1

I thought this would have definitely been fixed by now.. Can you find some specific email which is triggering this? It's either something strange that I didn't expect, or it's a bug in FreeBSD's iconv().

Also can you debug this like:

gdb --args doveadm index -u user@domain INBOX run <it should crash now> f 5 p src p ic_srcbuf p *src_size p srcleft I recompiled Dovecot with Debug but I suspect I will have to do it for all the required libraries as well; I did manage to find the offending message is in Trash but have not been able to pin-point which message it is. Just in case, here is the debugging info. I will see if I can compile all dependencies in debug mode as well.

recompiled dovecot + all dependencies with debug but I get the same output. anything else I can try?
