I don't know what it means to use Karatsuba for n = 1.

To use it from 2 to 5000, I'd do:

#define MUL_KARATSUBA_THRESHOLD          2
#define MUL_TOOM3_THRESHOLD              5001
#define MUL_FFT_THRESHOLD                5001

Please debug further problems locally before asking the list again.
If you don't know how to debug it, please ask for help locally.
