I'm using 3.7.0 - the one currently in debian testing. > If you still have a problem, ulimit -d .... will limit the total memory > used by Valgrind and the guest application. Tried that but that did not help. I'm also not entirely sure if it indeed is a leak in my program as I have a routine in it which constantly (20 times/sec) checks the memory usage (via /proc) of my program and does an exit() when it reaches 500MB (normally it should not use more than 120MB). If it is something in Xorg, would valgrind "see" this? I think it would (not sure, that's why I ask) as it would be the outcome of a call to it (via SDL/GL).
