Why do you just presume? If it were me, I'd go in there with a debugger and
check the actual memory bytes to see if that zero terminator is there or
not.
Also, your snippet didn't include where you allocate the space that the
gLabels handles point to; I'd check to make sure that that's being done
correctly and is ending up with what you expect.
Anyway, I'd bet a dozen donuts that the problem is occurring in the
HoleViewLoadDataFunc, and is probably related to those gLabels handles.
