You should add a short comment on the algorithm thus one can quickly
check it, e.g.
"No dependency if reminder of (l_start - r_start)/gcd(l_stride,
r_stride)) is nonzero."
At least it took me a short while to translate the GMP functions into
the string above.

(Additionally, I felt better, if you would add a run-test and include
also some checks that the temporary is still generated in some commen
cases. I am always worrying that on introduces bugs in such cases.)

OK with considering the nit above.
