Hi all,
thanks for the reply!
After seeing your reply I decided to thoroughly look through my own channel
draw callbacks, and I think I found the problem.
my draw callback looks something like that:
int
drawFunc(pfChannel * chan, void * data )
{
pfFog * fog = new pfFog();
....
pfEnable(...)
fog->apply();
pfOverride(...)
pfDraw();
pfDelete( fog );
}
Apparently it's the pfFog that causes the problem. It seems that pfDelete doesn't
clean up the memory properly. I took out the pfFog then the memories become
stable.
Although I am still curious why pfDelete doesn't work, I am now able to solve
the problem and finish my project. Thanks again.
