Is there any decent reading material out there about how exception handling is works under the hood and why it can't be done in a cross-platform way at the C level? From reading and participating in discussions about LDC, I've come to realize that implementing exception handling is a *much* harder problem than I would have anticipated, and I've become very curious as to why. Wikipedia would be the obvious place, but it doesn't seem to provide much detail.
