Any chance you can try the std.algorithm.sort? It may have more useful error
(or more consistent behavior at least).

Also, can you narrow down the code to a minimal example that causes the
undesired behavior?

It's possible there is an issue with the builtin sort. But sort really does
require that items it has already sorted are sorted. I'm not sure what steps it
assumes are correct.

An access violation doesn't seem like it should happen, but it's possibly due
to an optimization that is invalid with an invalid opCmp.
