Change Details

The left side of the MIN() expression is the (signed) result of pointer subtraction (ptrdiff_t). The right hand side is the also the (signed) result of pointer subtraction, additionally subtracting the element size ('es'), which is unsigned size_t. This coerces the right-hand expression into an unsigned value. (MIN(signed, unsigned) triggers -Wsign-compare.) Sorting elements of size greater than PTRDIFF_MAX is nonsensical, so we can instead treat the element size as ptrdiff_t, leaving the right-hand result the same signedness as the left.
