We found a bug causing performance problems for numbers between 2^64 and
2^127. It could also trigger asserts with factoring numbers close to
2^127.
The new version is attached.
Another bug found, this time related to the GMP code. It would clear
out an uninitialised structure with prime proving disabled.
Here ia a fixed version:

**`nt-factor-005.tar.lz`
