it seems that GPC ignores the upper bounds of $SUBJ when they are automatically converted to CString:

[pas]% cat slice.pas program Foo (Input, Output);

procedure Bar (S: CString); begin {$local X+} WriteLn (S) {$endlocal} end;

var S: String (20);

begin S := 'failedOKfailed'; Bar (S[7 .. 8]) end.

Thanks for the report. The problem was actually larger: Any assignment/parameter passing of a fixed string (i.e., `array ... of Char') to a CString did not get the #0 appended (so the CString just extended until the next 0 in memory, which here happened to be after the end of S). I've fixed this now (this means, the slice is now copied to a temporary variable where the #0 can be appended). (emil17.pas, fjf390[a-d].pas)
