When the sample Sender and Reciever are built with
VS.net 2003, a runtime error occures in
xltenc.c line 1115
due to pContent being an invalid (but not NULL) pointer.
The simple fix is to add
sync.meta = NULL;
to myStartSync in builder_wrapper.c before
return smlStartSync(id, &sync);
so the pointer is not mistaken for a valid pointer.
