Do you keep siocons active and connected while the program
runs? (Without this programs will freeze since the Yaroze seems to
wait for printfs to appear on siocons monitor)

Are the globals all externed properly?
Are you sure the new program space required by the globals
doesn't conflict with the data around the program (eg TIM files),
you can use mapfiles (GNU will generate these, see makefile
options and sample code) to see exactly how much space
the executable uses up.

Do you put the program stack onto the D-cache scratchpad?

Does the program freeze and never recover?
Can you pinpoint at what point of the program it crashes,
using printfs or the debugger (eg is it when calling a library function?)

PS why did you want to cut down on the number
of parameters to functions?

I recently finished the first cut of the game I've been working on.  I did
the programming using codewarrior and wanted to generate a version using
GNU.  While the program compiles ok, when I run it I'm having all sorts of
problems mostly with my program freezing up for no apparent reason.  I
believe the problem to be with my use of global variables that are shared
between the different C files.  In order to cut down on function parameters
I made a bunch of my variables global.  When I change these to be passed
parameters the program seems to work correctly.  The problem is I have a
lot
of global variables and I don't want to change all of them since this works
in codewarrior.  Anyone else run into a similar problem or have an idea as
to what's wrong?
