Problem with packed arrays of boolean in gpc20020402

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.
