Creating and saving a CDX index tag in the Table Designer after creating an IDX
index file causes the following error message:

In Visual FoxPro 6.0:

  Fatal Error: Exception code=C0000005

In Visual FoxPro 5.x:

  An application error has occurred and an application error log is being
  generated
  VFP.exe
  Exception:access violation(0xc0000005), Address: <memory address>

You may also see a Dr. Watson error message in Visual FoxPro 6.0, similar to the
one reported in Visual FoxPro 5.0.

Steps to Reproduce Behavior
---------------------------

1. Create a .PRG with the following code:

  CREATE TABLE idxtest (col1_c C(10), col2_i I)
  INSERT INTO idxtest VALUES ('one',1)
  INSERT INTO idxtest VALUES ('two',2)
  INDEX ON col2_i TO my_long_index_name  && create a IDX file
  MODI STRUCTURE
   

2. In Table Designer, select the Index tab.

3. Type in "Test" (without the quotation marks) for the name column and "col1_c"
  (without the quotation marks) for the Expression column.

4. Select OK to save the changes.

  Note that immediately after saving the changes, Visual FoxPro generates the
  Fatal Error and terminates.
