New subject: Problem with packed arrays of boolean in

15 Apr 2002


      The following test program demonstrates a problem with packed arrays of
boolean defined in a separate unit.  What I see is D reported as 0
followed by a segmentation fault.  The program works correctly if all
the declarations are in the main program.  I am using gpc20020402 based
on gcc 2.95.2 on Red Hat 7.2 using kernel 2.4.9-31 with an i686
processor.
Program PackedAssignTest;
Uses mltestu;
Var I,J:Integer;
    APackedBoolean:TPackedBoolean;
Begin
 ARecord.C:=99;
 ARecord.D:=100;
 ARecord.PackedBoolean:=APackedBoolean;
 Writeln('D=',ARecord.D);
End.
Unit mltestu;
Interface
Const MaxA=5;
      MaxB=62;
Type TPackedBoolean=Packed Array[1..MaxA] of Packed Array[1..MaxB] of Boolean;
     TRecord = Record
                 C:Integer;
                 PackedBoolean:TPackedBoolean;
                 D:Integer;
                End;
Var ARecord:TRecord;
Implementation
End.
