Hi,
I have seen the following assertion fails on my own mail server (indexer-worker):
Panic: file charset-iconv.c: line 132 (charset_to_utf8): assertion failed: (*src_size - pos <= CHARSET_MAX_PENDING_BUF_SIZE)
I've managed to narrow down the issue to one mail, and can reliably trigger the assertion with 'doveadm index -u user INBOX' with only that email. Maybe we should reset the iconv descriptor after each full conversion? i.e.: diff -r 91bbd6753689 src/lib-mail/message-decoder.c - --- a/src/lib-mail/message-decoder.c Thu May 14 23:49:12 2015 +0300 +++ b/src/lib-mail/message-decoder.c Fri May 15 22:52:41 2015 -0700 @@ -347,6 +347,8 @@ sizeof(ctx->translation_buf)); memcpy(ctx->translation_buf, data + pos, ctx->translation_size); + } else { + charset_to_utf8_reset(ctx->charset_trans); } output->data = ctx->buf2->data; output->size = ctx->buf2->used; Cheers, -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJVVuYpAAoJEJW2GBstM+nsrr8P+wZRjznaTJuAE7eaKlmO5Zba m9bUHsHh/rZdjfTCfUiwYwU66+EI8O2WEgr0sXynMrRhRWp5BVWMKGTl2loJ/oNL O3qXrGoVmAJoWmnd+ZQ49s+zSJUgXk9rJneN1i4erId6vjN1pcWXfrLbmeKhreN8 EmOMDO8WtV/XBq20UerKu+kGnatC8tNzpTQ5PCTnMc9z1nvNytE/NxM3Gli3wTRG 8nhZY8fS+y6guJfi68RZK6Th1W6jKQQW8+sNPlNbCRPxDb5delXLGq58DnQVk4mM Y6VxzQF4ItTU5h+ikNOaY7v4LoC3uydUdhPkMVVb5JVH+wx9en7PefhV4dH2MNjJ a8dJ4gvsYNBLZ1r3QLFF0NqJMhPXtidKLy7iQkBW0Z1LqmQrEpwZpLVGrdDtWLpA E4HkOmTMEyIbTuK5hG5zNyoF2+XLHSCAELZBHxJAxoHhwakm3n4MhJJao+aJho8+ DbgbGMFk4dDgvOAD0gqANSrIfpZkWGAzUiNiMP015Trg4bQm7CSztuvM6+xhr8EE zzvYjbeCAl3A1+u2q2UFaw8Ze60kD345FyRmkkxLxgJY3r32fSaU+1VvazlbIFKa zq4R2aospgIIxwVQOH3drqGgXpxEe54QG++3IQxmZyNCh3qocb+FnatVupHIJzX/ vvqgdswgAsXP04duqKKn =QaAX -----END PGP SIGNATURE-----
