Hi
I am testing gcc 4.6 and found what appears to be a bug. If I use
CryptoPP::AutoSeededX917RNG< CryptoPP::AES >
g_srandom_number_generator;
(any cypher fails)
Then it's a segfault (see below)
However switching to (which I do not want to do, or more likely
cannot)
CryptoPP::AutoSeededRandomPool g_srandom_number_generator;
Is fine, if not as secure.

I am not wishing to make too much of this as this is a beta release
OS, but it seems more of a cryptopp issue I think. Is anyone else
using ?
