#174 hfst-fst2strings segfaults or prints nothing

[Anonymous]

The transducer jokela.min.hfst is minimized and accepts strings:

$ hfst-lookup jokela.hfst
Ala-Jokela
hfst-lookup: warning: It is not possible to perform fast lookups with OpenFST, std arc, tropical semiring format automata.
Converting to HFST basic transducer format and performing slow lookups
Ala-Jokela [WORD_ID=Ala-Jokela][POS=NOUN][SUBCAT=PROPER][KTN=13][NUM=SG][CASE=NOM] 313.000000

Nevertheless hfst-fst2strings doesn't print any strings with option -r and segfaults with option -n

$ hfst-fst2strings -r 1 jokela.min.hfst
$ hfst-fst2strings -n 1 jokela.min.hfst
Segmentation fault

There seems to be something wrong with processing loops in the transducer. If you want n strings, try to limit the number of cycles to zero:

hfst-fst2strings -n 1 -c 0 jokela.min.hfst

Printing random strings seems to be broken, limiting the number of cycles doesn't help.
