Re: HEADS UP: OpenSSL problems after GCC 4.2 upgrade

there were several reports of OpenSSL being broken when compiled with

For the record (since I know several people were asking at BSDCan), this is
a great example of why it makes sense to have libmd as well as libcrypto: A
minimal hashing library which we maintain ourselves is far less likely to
randomly break than a bloated^W more feature-complete library which is
maintained outside of FreeBSD and occasionally imported onto a vendor branch.
