According to Sven Hilscher:

According to myself (Peter Gerwinski):

...

Better say `cmp: Pointer' here because you don't really know the type of the function `cmp' is pointing to.

No - IMHO qsort need always a function (cmp) that return an Integer, but the parameters/arguments of this function are pointers on different types.

True, but your `FuncType' points to a *parameterless* function which returns an integer. This is certainly a type conflict with the actual functions.

You found also the reason for the crash on sorting a "array of Byte"?

I cannot reproduce this one - neither with gpc-970714 nor with my current development GPC. :-( With which version and on which platform does it occur?
