If I comment this call, (replace with consoleWindow = NULL;) then it fails
few steps later.
It's just a symptom that we have broken something in the setup
I searched refs to alloca - like we return or pass a dangling pointer to
the local stack - unsuccessfully...
It might be worth to try again thru MSVC IDE (complementary warnings, stack
integrity checks, ...)
