[SDL] Win32/Linux SDL Differences

I had pretty much the same scenario here - an app working fine in Win32 but
Segfaults galore in Linux.

Rebuilding the app in debug mode and linking with electric fence (Debian
package is "efence") highlighted quite a few silly little problems.

It is - in fact - surprising that it ran on Win32 at all!

I've had similar problems, however it's the reverse. The win32 build works
perfectly, and Linux/MacOS faults. ;-( So far I have not been able to
prove this to be a problem of SDL, but rather of my code. So far it has
been because of lack of error checking when dealing with SDL. Double check
those errors! IIRC, There's a way to prevent SDL from trapping faults and
shutting down which might yield a backtrace that's useful.

And let's not talk about how bad it is going from DOS to any real OS. That
was a painful experience.
