I have a production system running on top of squeak and the vmcrashes after about 6 or 7 ours of testing, I need some help understanding the attached crash.dmp because i don't really know what's going on besides of what you can read on the stack dump, apparently theres is a problem with a BalloonEngine drawing primitive, i was wandering if somebody could provide me a hint on what could be failing...
Sure. From the exception code (C00000FD) we can learn that the crash is a C stack overflow normally caused by custom plugins or other external libraries having some sort of stack leak/corruption. From the loaded plugins we can see that you're using the FFI to do some stuff which leads me to suspect the problem is caused by one of your FFI calls (there is little reason to assume that one of the other plugins would cause this since they're used heavily in many production environments and have never shown such problems).
The first thing you should do is to very carefully screen your FFI calls. Are they declared correctly? Is the calling convention appropriate? Are the argument types correct? The other thing you could do to track this is to have a function which can return ESP from a primitive. In general the value should be identical when you call that primitive, so when it starts go differently, you're on to something.
