      Type:  bug       |         Status:  new    
  Priority:  high      |      Milestone:  6.8.1  
 Component:  Compiler  |        Version:  6.6.1  
  Severity:  normal    |       Keywords:         
Difficulty:  Unknown   |             Os:  Unknown
  Testcase:            |   Architecture:  Unknown
-----------------------+----------------------------------------------------
 Module `programs/cholewo-eval/Arr.lhs` in the test suite gives a Core Lint
 failure when compiled (no extra options apart from `-dcore-lint`).  This
 appears to be a regression from 6.6.1.  Simon PJ is looking into it.
