18 * test framework because the CRYPTO_mem_leaks_fp function cannot be called
19 * a second time without trying to use a null pointer. The test framework
20 * calls this function as part of its close down.

22 * A work around is to call putenv("OPENSSL_DEBUG_MEMORY=0"); before exiting
23 * but that is worse than avoiding the test framework's main.
