Shoot. I got the logic backwards. We want the test to exit with non-zero
status if c_stack_action fails (returns non-zero), or if recurse returns
(which should be impossible). The conditional should be written with ||,
not &&. At any rate, it confirms that c_stack_action is succeeding.
So, with my typo fixed, can you once again try those debugging steps, to
see if the breakpoint in overflow_handler trips?

That's what I've been figuring too - if we can get Irix 5.3 to work, then
all newer Irix will probably fall into place.

The issue still isn't resolved, no thanks to my typo...
