Re: Garbage collection causes stack overflow

[Fotis Panagiotopoulos <f.j.panag@...>]

Unfortunatelly not in my platform.

The stack overflow is detected by filling the stack with a known pattern, and then checking whether there are any data written to it. Thus the overflow is detected at a later time, not the moment that it is happening.

Maybe if I had more RAM (like a normal desktop computer), the problem wouldn't appear. But is this the way the GC is working? Does it use any kind of recursion? Or any large stack buffers?

Don't you have a stack trace?
