stderr doesn't exist, or point to a useful place, in many environments.
And a forced exit() is no better than a crash for most purposes.

The case that we are talking about is a bug, or would be a bug if it
could happen (the fact that we've gotten along happily with no similar
test in the existing code shows that it can't).  Many forms of bug can
result in core dumps; it's foolish to try to prevent them all.  And
bloating one line of code into five or more lines to defend against
can't-happen cases is a good way to end up with unreadable,
unmaintainable software.
