All:
I expanded the scope of the work for this bug and cleaned up other
realloc() errors in the windows native code. I believe I've identified
all unsafe calls to realloc() in this corner of the native code.
Two additional files were affected.
Please let me know what you think:

Thanks!

Kurchi,
if *netaddrPP == NULL at 367 and calloc fails at 391 we would jump
to freeAllocatedMemory with start == NULL
True, but then we skip to line 444 since *netaddrPP == NULL, so we don't get to
line 438.
I am just saying it is not strictly necessary to check if start is null before
entering the first if block. We might want to guard against how the code
changes in future and put in the check though.
I have no ideas whether this code path is possible in reality or not,
but it stops my eyes.

John,
102, 145 else is redundant.
438 - we will crash here if start is null
Maybe it is good to have an additional check for start != null, but from what I
see, start will not be null if *netaddrPP is not null.

John,
I see bad realloc pattern here. Could you fix it as well?
Yes, please. Otherwise the changes look fine.
-Chris.
e.g.
93 adapterInfo = (IP_ADAPTER_ADDRESSES *) realloc (adapterInfo, len);

I fixed a case in the windows native code where calloc() was being used
without checking it's returned value.
