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
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 :
It 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 :
The 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 one
of my user reported me to get the bug, even after have disabled the creation

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

Anyone would have some idea where and how I should head my bug research ?
Thanks in advance…!
