Calling sys:call recursively may blow the C stack

[kvverti]

Because sys:call is intrinsic, it uses the C stack instead of the Lavender stack. Recursive uses of sys:call are able to overflow the C stack, resulting in a segmentation fault.

Trigger:

def f(a) => sys:call(a, {a})
f \f

Presumably, calling other intrinsic functions recursively may also blow the C stack. I think sys:call is the only function that allows unbounded recursive intrinsic calls, though.
