still nothing... by adding some WriteLine's I could manage to get this:

Bus error

I was able to create a Form with some controls in it, but when I call
Application.run() that exception occurs and then I get the bus error. This
is with one of my test programs, which by the way, wasn't able to create a
TextBox. I get this exception:

this comes up when calling the TextBox's no-arg constructor.

I don't know if anyone else is getting something similar on other
platforms...
