- Trap after Info->Analyze Module

Hi all,


I have this simple module:




MODULE TrialsAnalyzerTrap;

 

                PROCEDURE Sub1 (a: INTEGER);
                BEGIN
                END Sub1;

 

 

                PROCEDURE Sub2;
                                VAR i: INTEGER;
                BEGIN
                                Sub1 (i);

 

                                FOR i := 0 TO 2 DO
                                                Sub1 (i)
                                END

 

                END Sub2;
END TrialsAnalyzerTrap.

 

 

The code contains an error: when Sub1 is called the first time within Sub2 the variable i is not initialized.

When I call Info->Analyze Module I get an invalid case trap:

 

invalid CASE

 

 DevAnalyzer.UseObj [00001098H]
.markUseBSet BOOLEAN TRUE
.obj DevCPT.Object [011032F0H]
.pos INTEGER 166

.id DevCPT.Object NIL

.lastp DevCPT.Node NIL
.moreThan1 BOOLEAN FALSE
.n DevCPT.Node NIL
.newPar DevCPT.Node NIL
.pre DevCPT.Node NIL
 DevAnalyzer.StatSeq [00005E02H]


Did I do something wrong or could this be a hint to a problem in the analyzer code ?
I'm still working with BlackBox 1.5; may be this effect does not show up in BB 1.6.

Best regards,
