COMPILE XREF of code using TABLE-SCAN crashes session

COMPILE XREF of code using TABLE-SCAN crashes session.

COMPILE XREF of code featuring a TEMP-TABLE with a PRIMARY, UNIQUE index that is queried using TABLE-SCAN crashes session.

XREF file is created but is empty.

Stack trace from PROWIN reads:

stbcmp
smwhr
smwhere
profcomp
fdfcomp
smdbsp
smbkst
smsem
cr_compile
...

The problem does not occur when:

• the code is in a .P.
• if the primary, unique index of the TEMP-TABLE is removed.
• if the TABLE-SCAN specifier is removed from the query.
• if the XREF option is not used with the COMPILE statement.

Sample code:

/* Crash.cls */
CLASS Crash:

   DEFINE PRIVATE TEMP-TABLE ttPropertyDropDown NO-UNDO
      FIELDS cName AS CHARACTER
      INDEX PKey IS PRIMARY IS UNIQUE
         cName
   .

   METHOD PRIVATE VOID EmptyDropDownTT():
      FOR EACH ttPropertyDropDown WHERE
         ttPropertyDropDown.cName = "name":U
      EXCLUSIVE-LOCK TABLE-SCAN:
      
      END.
   END METHOD.

END CLASS.

Compile statement:

COMPILE Crash.cls XREF "Crash.xref".

 

At compile time, the AVM checks if a string was WHOLE-INDEX and no check was done to see if it is null.

Upgrade to OpenEdge 12.2 where before the AVM compares to see if the string is WHOLE-INDEX, it checks if it was null.

Remove the TABLE-SCAN option from the query when otherwise a WHOLE-INDEX would be used by the compiler.
