[Xapian-discuss] seg fault on search

[Michael Lewis]

I have written a very simple function to return the match count based on the simplesearch.cc code. It fails with a seg fault. The relevant code is:
--------------------
int ftQuery(char* qs, const char* dbname,char* results, int msize) {
        long            docid;
        char*           op; 
        char            fullDB[1024];
        string          queryString;

        sprintf(fullDB,"/var/lib/fulltext/%s",dbname);
        queryString=qs;
    try {
        Database db;
        db.add_database(Database(fullDB));
        Enquire enquire(db);
        try {
                Xapian::QueryParser qp;
                Xapian::Stem stemmer("english");

                qp.set_database(db);
                qp.set_default_op(Query::OP_OR);
                qp.set_stemmer(stemmer);
                qp.set_stemming_strategy(QueryParser::STEM_SOME);
                Xapian::Query q=qp.parse_query(queryString);
...

As soon as it hits the q=qp.parse_query line it gets the seg fault. 

The function is called like so:

int main (int argc, char* const argv[]) {
        int     i;
        char    results[100000];

        if (argc<2) {
                printf("Usage: tft 'query string'\n");
                return 1;
        }
        I=ftQuery(argv[1],"testdb",results,2000);
        printf("%d results returned\n",i);
        return (0);

The query string is "austria" and it works with simplesearch.com. I have verified that the string is being passed to the function correctly as is the database name. I am out of ideas and wonder if anyone can point out anything that I am overlooking.

Thanks,

Michael Lewis
