Please try this with the latest redland 0.9.19 released 2004-11-01
which includes rasqal 0.9.4, not 0.9.2 that you are using here.

Only rasqal_engine.c in rasqal 0.9.2 has the line numbers that match
what you gave, for example:


> #13 0x407482b6 in rasqal_free_triples_match (rtm=0x80a6870) at 
> rasqal_engine.c:376

is at:

374: static void
375: rasqal_free_triples_match(rasqal_triples_match* rtm) {
376:  rtm->finish(rtm, rtm->user_data);
377:  RASQAL_FREE(rasqal_triples_match, rtm);
378: }
