Bug 677386 – app-crypt/dieharder: some tests fail incorrectly on 64 bits OS

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description vm666 2019-02-06 18:53:40 UTC]

"dieharder -g 500 -a" for /dev/random and "dieharder -g 501 -a" for /dev/urandom will fail on 64 bits systems at least.
Linux PRNG is perfectly fine, this is a bug in Dieharder. AFAIK there is no fix upstream, so we should patch it, at least temporarily.
This bug was also reported on RedHat.
