AK-index segfault

Scope of problem

I've tried to reproduce this bug, and it appears to be fixed in the 2.6-6 release of the GPL OpenQM GPL. Hence it should also be fixed in the CVS, but nobody has checked yet.

As of 22Jun12, this bug has been verified as fixed in the current source tree (Revision 98).

Steps to reproduce

Create a file called TESTFILE with a dictionary entry F1 of:

1: D
2: 1
3: 
4: F1
5: 5R
6: S

Now run this program to get some data in:

 open "TESTFILE" to file else stop
 
 for i = 1 to 2000
   data = i
   write data to file, "rec":i
 next i
 
 data = ''
 for i = 2001 to 2100
   write data to file, "rec":i
 next i
 
 end
 

Now

SELECT TESTFILE WITH F1 > 1500

works fine;

CREATE-INDEX TESTFILE F1
BUILD-INDEX TESTFILE F1
SELECT TESTFILE WITH F1 > 1500

Segfault.
