Line txtidx.c:366 :
lemm = lemmatize(token, &lenlemm, type);

lemmatize() is defined in morph.c. Did you use another modules for postgresql?

It seems to me that we see a name conflict. Function lemmatize is defined in somewhere also.

Pointers 0x40* - functions in tsearch.so, 0x08 - postgres file.

So first string '#0 0x02d10000 in ?? ()' has pointer to 'black hole'..... Very strange....
