You used to be able to get the OCaml compiler to segfault by using -rectypes
inconsistently while compiling. I believe that -rectypes can be useful. For
example, the OCaml implementations of the ray tracer benchmark use it to good
effect to implement the scene tree without an extra level of indirection. I
have never bothered turning it on for any significant projects or during
development though, so I can't say with any certainty whether or not it has a
practical impact on error messages.
