--- Comment #13 from Juan Lang juan.lang@gmail.com 2011-10-23 15:44:00 CDT --- The thing is, it doesn't look like there's anything wrong with the code in iphlpapi. A buffer is allocated; it isn't null; when reading it an access violation happens. So that's why I wonder whether something else has corrupted the heap beforehand, and iphlpapi isn't the source of the problem.
