Ok, I nailed the bug, but i'm not sure what the correct fix is. Attached tsearch_morph.diff that remedies this problem by avoiding it. Also there's a debug aid patch if someone would like to know how i finally found it out :)
There problem in the lemmatize() function is that GETDICT(...) returned a value not handled (BYLOCALE). The value (-1) and later used as an index into the dicts[] array. After that everything went berserk stack went crazy somehow so trapping the fault sent me to the wrong place, and every time i read the value it was positive ;) So now i just return the initial word passed to the lemmatize function, because i don't know what to do with it. So you tsearch guys will have to work it out :) Magnus
