Have you reviewed past discussions about valgrind and OpenSSL?

In general, memory-use checkers such as valgrind's memcheck are going to be suspicious of some aspects of OpenSSL, which makes some assumptions about memory that it knows are suitable, but which cannot generally be verified by typical static or dynamic analysis.
