You probably ran the VM out of memory with an infinite
recursion. The "stderr" window is generally only opened
when the VM hits some situation that it can't handle. It
sometimes provides a clue about what happened and thus
helps in VM debugging.

You can simply quit from Squeak, recover (using the
change log), and fix the infinite recursion. Incidentally,
you're supposed to a low-space notifier when you have
an infinite recursion, but if a problem occurs in the
code that puts up the low-space window the low-space
notifier itself may run out of space. At that point, the
VM really has no memory, and it just crashes.
