I've posted about the WebSSL memory leak before. In short, it is this line:

CRYPTO_set_mem_functions(SSLAlloc, SSLRealloc, SSLFree);

If you comment it out there shouldn't be a memory leak warning anymore, even though it is actually still there.

For a permanent fix, all the correct openssl unload functions should be called. I will check it out myself later, but for those in a hurry; see http://www.openssl.org/support/faq.html#PROG13 for more information.

Hello phirox

This is a really old U++ bug ! Confused

.

You discovered it in 2008 and it is not solved yet.

I found the same bug some months ago as I posted here: http://www.ultimatepp.org/forum/index.php?t=msg&goto=257 72&

It is an OpenSSL cleanup problem.

Other way to solve it would be to do this in Web/SSL/util.cpp:

INITBLOCK {
	Socket::Init();
	CRYPTO_set_mem_functions(SSLAlloc, SSLRealloc, SSLFree);
	SSL_load_error_strings();
	//SSL_library_init();		//SOLUTION TO MEMORY LEAK !!
}

That's not work. Without "SSL_library_init();", SSL context cannot be created (SSL Context Error in result). I can't run the secured server without this line(

ENGINE_cleanup() - also not helps.

Another variants?
