2) Improve documentation and visibility of this problem. For example,
add this to the documentation of sort:

"The predicate must be transitive (`a<b && b<c` implies `a<c`) in order for `sort` to behave properly - otherwise, the program may fail on certain inputs (but not others) when not compiled in release mode. Note that `a<b` is not transitive for floating points, because the expression
will always be `false` when either `a` or `b` is `NaN`."

Great idea, just file an enh request or just write the pull request.
