Comment(by midnightmagic):

 It would be interesting if it were flakey hardware, since the same problem
 happens pretty uniformly across otherwise stable and independent machines
 that have similarities: they are x86, pretty old CPUs, etc. (Like, one is
 crazy rock-solid stable up for 600+ super busy days machinery, so solid I
 run a strata 2 ntp on it.)

 I downloaded and built crypto++ manually, and running the tests as bdew
 did I found 100% success so long as I kept the /dev/random entropy pool
 fed. (Else it would fail because it would wait too long for random data to
 appear.)

 I will attempt these other things that bdew seems so facile with. :)
