I tried to use  _alloca, still same error. Also tried wdk version 6001.18002, still got the error.
What is your wdk version?

This builds fine here. Perhaps you are using a combination of VCC and
WDK which does not fit together? Google shows some hits when searching
for "__alloca_probe_16 unresolved external".

You could also try to replace alloca in


by _alloca.
