Comment (by dfeuer):

 Replying to [comment:1 Lemming]:
 > I think a hard crash is completely appropriate. Bound violations are
 programming errors thus there is no way to safely recover from them,
 anyway.

 My concerns about the "hard crash" approach: the error messages may not be
 as informative as one might wish, it may be tough to get the error
 messages in some environments, and I don't know if there would be any
 challenges ensuring that other application threads get killed. But I do
 think it would be a lot better to have that as an option than to have
 nothing.
