Module failure 

Why running an app’s code can fail. The interpreter and compiled apps both report these, so an app fails the same way however it runs.

Constants

MAX_CALL_DEPTH

How deeply functions may call each other before the app stops with an error. The interpreter takes roughly 10 KB of native stack per call in debug builds, so this stops runaway recursion well before a 2 MB thread stack overflows.
