Bug #6267: Segmentation fault when exponentiating complex number

[pabloh (Pablo Herrero)]

A segfault is raised when running the following script, with any exponent greater or equal to 5:

require "mathn/complex"
Complex(0,1)**5

It only seems to happen when exponentiating pure imaginary numbers and if 'mathn/coplex' is loaded, otherwise it works just fine.

Pablo, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
