DRIVER_VERIFIER_DETECTED_VIOLATION (c4)
A device driver attempting to corrupt the system has been caught. This is
because the driver was specified in the registry as being suspect (by the
administrator) and the kernel has enabled substantial checking of this driver.
If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will
be among the most commonly seen crashes.
Arguments:
Arg1: 00000014, the pool the caller is trying to free is already free.
Arg2: 00001b5e, (reserved)
Arg3: 8a9104f0, pool header
Arg4: 00000000, pool header contents
