I wish it was that simple... Unfortunately, it will not throw - a managed
exception. It triggers a native segmentation fault or something along
these line and unrecoverably crash the CLR process, because the problem
occurs in native code.

Sure, the managed wrapper should protect the unmanaged code, and prevent
the managed code from doing undefined unmanaged operations. Alas, taking
such things as multiple CLR threads, and other such funny as managed
thread cancellation, makes this pretty difficult, if at all possible.
