Cleanup OpenSSL_add_all_algorithms()

[1992]

Good day,

can somebody please say me, how to cleanup OpenSSL_add_all_algorithms()?

I have a constant memory leak with the code in the attatchment.
The valgrind log is also there.


My secound problem:
==32205== Conditional jump or move depends on uninitialised value(s)
==32205==    at 0x51424D9: BN_bin2bn (in /usr/lib/libcrypto.so.1.0.0)

Is there an ability the mute valgrind for those functions?

Sincerely yours


#include <openssl/bio.h>
#include <openssl/ssl.h> 
#include <openssl/err.h> 
#include <openssl/conf.h>
#include <openssl/engine.h>


int main(int argc, char** argv) {
	OpenSSL_add_all_algorithms();
	
	ERR_remove_state(0);
	ERR_free_strings();
	
	ENGINE_cleanup();

	EVP_cleanup();

	sk_SSL_COMP_free( SSL_COMP_get_compression_methods() );

	CONF_modules_finish();
	CONF_modules_free();
	CONF_modules_unload(1);
	
	CRYPTO_cleanup_all_ex_data();

	return 0;
}
