OK, that more or less confirms that it is the stack issue.

It's "normal" in the sense that if you don't have enough stack, test 2
fails. What is "enough" depends on the OS and the hardware in ways that
I do not understand. In situations where there is only 8MB of stack, it
sometimes works, sometimes fails.

My guess is that the stack usage is close to your default (which I'm
guessing is 8MB). Adding the zlib stuff pushes it just over the limit.
That's just a guess, of course.
If you can figure out how to increase your stack size, you could try
that without --disable-stack-for-recursion.
