To reply my own question. :-) The problem is that gcc does sign extension to the value. Changing to value less than 0x7fe fixed the problem.

If this is the case, you should also be able to solve the problem by specifying the address as unsigned, e.g.
((func_type) 0x1D400U)(); Note the 'U' suffix. Haven't tried it, though... Regards, -=Dave _________________________________________________________________Get today's hot entertainment gossip http://movies.msn.com/movies/hotgossip?icid=T002MSN03A07001
