Comment(by guest):
As an additional data point, I modified the sample program to call
`mallocBytes`. This is what I discovered:
* `mallocBytes` throws a "resource exhausted (out of memory)" exception
* the exception is catchable
So it would be possible to fix the `alloca` family of functions by
implementing them in terms of `mallocBytes`. I think for now in the
programs I write I'll use `malloc` and avoid `alloca`, as a workaround for
this bug.
