Apparently it's in SSLeay_add_all_algorithms();
I found it by removing code portions successively.
If you make a win32 console app that calls the 2 functions below in
sequence, and compile it in the debug version, you'll see it. Move the call
to SSLeay_add_all_algorithms out of the #if 0 portion, and you'll see the
leaks.
int OpenSSLStart()
{
#ifdef CRYPTO_MDEBUG
_CrtSetDbgFlag(_CRTDBG_REPORT_FLAG); /* win32 specific */
#endif
/* init error BIO */
pBioErr = BIO_new_fp(stderr,BIO_NOCLOSE);
if (pBioErr == NULL)
return(1);
/* init OpenSSL debug tools */
//#ifdef CRYPTO_MDEBUG
#if 0
CRYPTO_malloc_debug_init();
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON);
#else
CRYPTO_malloc_init();
#endif
/* load error strings & all crypto algorithms */
#if 0
ERR_load_crypto_strings();
SSLeay_add_all_algorithms();
#endif
return(0);
}
void OpenSSLStop()
{
EVP_cleanup();
ERR_remove_state(0);
ERR_free_strings();
/* print mem leaks */
//#ifdef CRYPTO_MDEBUG
#if 0
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF);
CRYPTO_mem_leaks(pBioErr);
#endif
BIO_free(pBioErr);
#ifdef CRYPTO_MDEBUG
_CrtDumpMemoryLeaks( ); /* win32 specific */
#endif
}
