I've created a software which performs the Fermat's Primality

why?
I've used GDB and here is the message:
Program received signal SIGILL, Illegal instruction.

Here is the link to the source code:

Another point.. never use std.bigint for something serious.
At first you can try to use https://code.dlang.org/packages/gmp-d
and see if the problem is still presented
