Subject: Initialize "buf" to 0 to make valgrind happy :-)
X-Git-Tag: FIPS_098_TEST_1~55^2~7
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1364e6f1ac1d0aec831b936bc5cfc83211e74495;p=oweals%2Fopenssl.git

Initialize "buf" to 0 to make valgrind happy :-)
Note: the RAND_bytes() manual page says:
 RAND_bytes() puts num cryptographically strong pseudo-random bytes into buf.
It does not talk about using the previous contents of buf so we are working
as documented.
