For debugging the Ruby/OpenSSL library. Calls CRYPTO_mem_leaks_fp(stderr). Prints detected memory leaks to standard error. This cleans the global state up thus you cannot use any methods of the library after calling this.
Returns true if leaks detected, false otherwise.
This is available only when built with a capable OpenSSL and –enable-debug configure option.
Example
Example
OpenSSL.mem_check_start NOT_GCED = OpenSSL::PKey::RSA.new(256) END { GC.start OpenSSL.print_mem_leaks # will print the leakage }
