revolution crash on revdatafromquery on 3.0 mac os x

[Andre Garzia]

Mark,

Thanks for the reply. I know I am one of those guys that keep trying
to do complicated stuff with the engine but in this case I was doing
the most standard thing ever. I opened a connection to a remote MySQL
server at dreamhost, it returned an id as expected and then issued a
simple revdatafromquery call and it broke. After repeating this five
times, I decided to launch from the console to see if something worthy
appeared there and glued the output here.

Two lines only, one opens the database, another one calls... and it explodes.
(MySQL params are right and accounted for)

Any clue?

Andre
