Hi Laszlo,
I think there may be a bug: Variable.c
Look
-------------------
NewLoadContext->ForceReconnect = (BOOLEAN) (NewLoadContext->Attributes &
LOAD_OPTION_FORCE_RECONNECT);
-------------------
But LOAD_OPTION_FORCE_RECONNECT == 2 and BOOLEAN == UINT8
so ForceReconnect will be 2. Then
--------------
*((UINT32 *) Ptr) = LOAD_OPTION_ACTIVE | (ForceReconnect << 1);
--------------
I am not sure it is a bug but I think it should be corrected as
-------------
NewLoadContext->ForceReconnect = (BOOLEAN) ((NewLoadContext->Attributes &
LOAD_OPTION_FORCE_RECONNECT)?1:0);
-------------
Wishes,
Sergey
