[Dovecot] sieve 0.1.8 raw backtrace

[jsechser at gmx.ch]

hi,

I had two problems with deliver / sieve.
First one is not reproducible anymore.

Im using debian unstable (amd64), often dist-upgraded, with some experimental 
stuff too (wine i think).

The first basically triggered a backtrace when confronted an email with 
spammassassins report headers prepended. (user_prefs: report_safe 0)
However i dont have that backtrace anymore, sorry.

The second poped up only later as i began to investigate more the first, a few 
days later. Now my entire sieve script seemed broken suddenly. After some time 
i narrowed it down to one offending line:

>require ["fileinto","regex"];
>
>if address :regex "to" ["m-a-test at test\\.ch","m-a-members at test\\.ch", \
>"m-a-region at test\\.ch","m-a-sig at test\\.ch"] {
>        fileinto "Test";
>        stop;
>}


if i remove even one of the regex tests, then this script will not make 
deliver or sieve_test go panic.

here the backtrace:

frame changed
