Hi, I'm having a problem where my program fails with error: /home/john/projects/chapel/chapel/modules/internal/ChapelArray.chpl:165: error: attempt to dereference nil
I haven't had success in trying to isolate the problem so unfortunately I don't have a simple example file which would reproduce the problem. However I have a test in my git branch of chapel which causes the problem. The branch in question is here https://github.com/jfrenz/chapel/tree/VariBlockDist The failing test is located at test/distributions/jfrenz/block-variblock/simple-coexist.chpl . If you comment out either of the forall loops in that file it runs fine. I have had it fail at least with GASNET_SPAWNFN=L and two or four locales. In that git branch I have modified only files in modules/dists , modules/standard and in test .
