Memory Leak using CertOpenStore on Windows 2008 R2

-

i have program (runs both 32 , 64 bit ) when using certopenstore results in memory leak on windows 2008 r2 (i haven't tried 2012, code has run years on 2000, 2003, 2008 without issues)

sample code reproduce issue:

int main( int argc, char** argv )  {  	hcertstore store;  	int go = 1;    	while( go ){  		store = certopenstore(   				cert_store_prov_system_a,   				0,   				0,  				cert_system_store_local_machine | cert_store_open_existing_flag,  				"my" );  		if( store ){  			//if( !certclosestore( store , cert_close_store_check_flag ) ){  			if( !certclosestore( store , cert_close_store_force_flag ) ){  				if( getlasterror() == crypt_e_pending_close ){  					printf( "!" );  				}  				else{  					go = 0;  				}  			}  		}  		else{  			go = 0;  		}  		sleep( 10 );  	}  	return 0;  }

the callstack allocations pretty  (this 32 bit process on 2008r2 box)
