Wrongly formatted blocktrans content example:

This will cause blocktrans tag to go to infinite recursion of death possibly leading to out of memory for the whole server.

It definitely should not crash like that.

Just as a side note, Python has a fixed recursion limit (see sys.getrecursionlimit), so no, it won't use up all of your server's memory.
