I just noticed that the SQLite module in 7.7 will segfault if you run a query that returns zero rows (as opposed to a query that throws an error). Since it uses some array aggregation magic i don't fully understand, I thought I'd leave it to someone else. Seems like a pretty major bug, though:
object s= Sql.Sql("sqlite:///tmp/speedydelivery.sqlite3"); s->query("select * from lists where name=0");
Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x0000000c 0x006d276f in f_SQLite_query (args=1) at sqlite.cmod:326
