that means to say, the parameters are for checking at a macro level and IsHeapPointer() is a more detailed check? Is it ok, if an address is validated to be a legal GC heap addr (but since there might be gaps inbetween it is actually does not belong to any of the spaces) this situation might occur since threads.h defines a function IsObjRefValid that doesnt call IsHeapPointer() and uses only the lowest and highest addresses to decide. > thank you, > archana
