I'm seeing OpenSSL failures when building this branch, but I don't see them when building current trunk Ruby on the same EC2 instance - maybe one or more missing commits?

Here's what I'm seeing a bunch of:

Noah, thank you for reporting. I see stack-rtl-mjit-base (a trunk at some point in Dec) has the same problem. I think the next round of merge with trunk would solve the problem. I've chosen a wrong version of trunk to merge with. I should have been more careful with choosing a merge point.

Always lookup IV buffers when iterating
2d86e79 
Always look up instance variable buffers when iterating.  It is possible
for the instance variable buffer to change out from under the object
during iteration, so we cannot cache the buffer on the stack.

In the case of Bug #19095, the transient heap moved the buffer during
iteration:

```

```

In general though, any calls back out to the interpreter could change
the IV buffer, so it's not safe to cache.
