Hello,
I just finished to port 2 of my games to Mac OSX from
Windows/DirectX/D3D, using SDL v1.2.12 + SDL_image v1.2.6 + SDL_mixer
v1.2.8, with OpenGL for display.
Unfortunately, both games get random crashes, sometimes just at start
or after a few minutes, sometimes after a hour, sometimes never.
Unfortunately, on my system, it seems to be never, so it's not easy
for me to debug and find the cause.
I gathered a few crash reports I got here :
http://www.managames.com/crashreports.htmlIt seems the crash occures from the Cocoa event system, both with
nextEventMatchingMask & sendEvent, by wanting to reach an incorrect
object address, and thus crashing in
objc_msgSend (or objc_msgSend_rtp).
My games are in C++, so I'm using only 2 obj-c sources (one being
obj-c++), I put them here :
http://www.managames.com/crash-mm-code.txtThe 1st one is the SDL default file. I tried both with and without
using a custom .Nib file.
The 2nd one is mainly used to add a custom menu with a few entries,
but 2 of my users reported me to still get the random crashes, even
after have disabled the creation of this menu.
I got some few crash reports from within my code, and I already
corrected them, but it didn't help to fix the random crashes...
On my system, I used NSZombieEnabled, CFZombie, MallocGuardEdges &
MallocScribble, without any result.
I have my own buffer overrun detection system in debug mode, and it
didn't catch anything.
After the initialization, there's no more Cocoa activity from my
code, it's only C++.
2 more points:
- it still crashes with the sound off
- it seems to crash a lot more often in fullscreen than in windowed mode
You can find my games here :

Thanks in advance..!
