[SDL] Mysterious(ish) segfault

[Michael Samuel]

Sam, you already have some code that will produce this error, but here's a
cleaner version, now that I understand what I'm doing ;-)

I'm trying to implement a simple missile control game (eg. blast that missile
flying overhead... very simple, and hopefully very addictive ;), and it seems
to segfault every now and then.

It currently seems to track down to line 65 of the code, except sometimes it
gets past that stage (especially when I run it under gdb), and sometimes it
segfaults a bit later...

I have a tarball with what I have so-far at 
http://sal.nb.surfnetcity.com.au/~michael/src/missile_control.tar.gz (that's
only a 33.6 link, so don't all download it at once ;-).  Also, ignore the
somewhat boring looking graphics, I just wanted to test my code and put cool
graphics in later ;-)

(tarball is 2925 bytes, 932318 bytes uncomressed)
