Given the error message below, is there an indication of the file/position of the code responsible?

If you "Copy" the trace, and then switch to the IDE and choose Go to -> Go to Position On Clipboard Shift+F2 then you can easily access the lines mentioned in the dump (double clicking on lines and using F8/Sift+F8).

Anyways, string(398) is here:

Code: Select all

clauses
    front(Source, Position, First, Last) :-
        checkPosition(Position, Source),
        First = create(Position, Source),
        Last = uncheckedConvert(string, uncheckedConvert(integerNative, Source) + sizeOfDomain(char) * Position).

You are trying to take the first 6 characters from a string that is only 4 characters long. The dump may have revealed where string::front was called from, but that is not visible in the image.
