Hi All,
I called this function twice in my test program and it crashes in second call inside dst_lib_init()
Can you please help in finding the issue here. Seems like some sort of memory issue
void calltoentropy()
{
CCryptoTools::InitializeOpenSSL();
isc_mem_t *mctx = NULL;
dst_key_t *keyp = NULL;
isc_result_t retStatus;
// setup required stuffs
retStatus=isc_mem_create(static_cast<size_t>(0), static_cast<size_t>(0), &mctx);
isc_entropy_t *ectx = NULL;
cout<<"Before isc_entropy_create ectx is "<<ectx<<"and address of ectx is "<<&ectx<<"return status is "<<retStatus<<endl;
retStatus=isc_entropy_create(mctx, &ectx);
cout<<"after isc_entropy_create return status is"<<retStatus<< " mctx::"<<mctx<< "and ectx"<<ectx<<" and ectx address"<<&ectx<<endl;
retStatus=dst_lib_init(mctx,ectx, static_cast<size_t>(0));
cout<<"dst_lib_init"<<retStatus<<endl;
isc_entropy_detach(&ectx);
cout<<"isc_entropy_detach "<<ectx<<"-"<<&ectx<<endl;
dst_lib_destroy();
cout<<"dst_lib_destroy()"<<endl;
if ( ISC_R_SUCCESS == retStatus )
{
cout<<" ISC_R_SUCESS is return status"<<retStatus<<endl;
}
else
{
cout<<"just return"<<endl;
}
Output
