Yes, it's because D exceptions are not guaranteed to propagate 
through the C callstack. It works on some compiler/platforms, but 
not others. I wrote an article at Gamedev.net (which apparently 
no longer picks up the site's stylesheets) which shows one way of 
dealing with it. I've modified my approach since then (and should 
write a better article about it), but the basic idea still holds.
