The Gmp-functions don't have a correct behaviour:
pow(2, pow(2, pow(2, pow(2, pow(2,pow(2,2))))));
Compiler Error: 1:Error evaluating constant. Compiler Exception: Too many argumentsUnknown program: pow(HilfeCompileHandler,-1,-1)
There are only two arguments there! And there should be some sort of space in "argumentsUnknown"
pow(2, 65536423423423423);
(7) Result: 65536423423423423
8->pow(34534534534534534534534534545);
Gmp.mpz->pow: Non int exponent. /usr/local/pike/7.3.43/lib/modules/Gmp.so.bignum: pow(34534534534534534534534534545) HilfeInput:1: ___HilfeWrapper()
Seems OK, but "Non int exponent." could be changed to "Exponent bigger than a non-bignum integer.".
8->pow(34534534);
Segmentation fault
Not good! I think this is an out of memory problem, so you have to change 34534534 to something that works on your computer.
