Unfortunately I can't give you any advice, just a confirmation: I have
the exact same problem: I had an app running nicely on 6.0. Buying a new
machine, installing 6.2. Compiling went ok and the program runs only
partly. If I take the binary from 6.0 it complains about some
incosistence, but runs correctly. The binary from 6.2 hangs at some
point, though.

Does anybody know how to update the compiler? I am a halfway newbie with
linux, so be gentle..
