That is very strange. Some parts of that structure are intact while
others are garbage. Either somehow that structure is hanging around and
being freed up twice (which shouldn't be possible if the reference
counting is correct) or something is corrupting it.
Can you tell me which configuration options you used for all the
packages (Apache, Curl, PHP, OpenSSL and anything else relevant) so I
can try to reproduce that here?
Steve.
