I really, really hope that you can't recover from seg faults on
Windows (or MacOS for that matter). Segmentation faults should be
non recoverable: once the program has started accessing memory that
it shouldn't, there is no way to guarantee that the program is in a
coherent state. Walter has stated this several times and I agree
with him 100% on this.
