Problem seems to be an occasional overflow with gmp.


This works as expected:

> echo '' | awk -M '{print 200000000000000000000000000000000000000000 *
200000000000000000000000000000000000000000 ^ 20000000000000000000}'

> +inf


This crashes:

> echo '' | awk -M '{print 200000000000000000000000000000000000000000 *
200000000000000000000000000000000000000000 ^ 2000000000000000000}'

200000000000000000000000000000000000000000 ^ 2000000000000000000}'


Should be noted the crash is a slightly smaller number than the larger.
