possible bugfix for 1.1.90 and 1.1.91

[Brieuc Jeunhomme]

Hi,

I was doing some tests with 1.1.90 and I have found what seems to be a
memory leak (or maybe I don't use the library the right way?).

The attached patch fixes the leak (for those who don't like reading diff
files as I do, grep for 'fixed by BBP' in 'primegen.c' after applying
it).
