That's not the correct fix.

The correct place to fix is getIpAddrTable in ifenum.c, so that should it fail, it frees the memory it allocated. This was obviously an oversight on my part. See the for loop here:

http://source.winehq.org/source/dlls/iphlpapi/ifenum.c#L735

This loop terminates if something fails, so after the for loop is an ideal place to add a HeapFree. In this way, the callers (GetIpAddrTable is but one) never have to cope with freeing memory when getIpAddrTable fails.
