I'm seeing this on Windows as well. I let it run for about 10 minutes before killing it. The last 3 tests run on the largest value of "p". I skipped these tests by modifying the 01-dh.t and removing the last entry from the @pgs and also adjusting the planned tests down by changing this line: Test::More->import( tests => 18 + ($has_pari ? 3 : 0)); to this: Test::More->import( tests => 15 + ($has_pari ? 3 : 0)); The first 3 keys are 256 hex characters and the last entry is over 1000 hex characters. I assume that generating such a long key pair is very CPU intensive.

I just tried this again on a more powerful quad core CPU and all 21 tests passed every about 15 minutes. So, I guess it's just a matter of processing time.
