Run the mri-fhd parboil benchmark with and without loop unrolling in the\r\ninner loop. What is the expected output? What do you see instead? 1. With unrolling, the kernel produces incorrect outputs starting with the\r\nfirst ld.const compared to the same kernel without unrolling. What version of the product are you using? On what operating system? Ubuntu 9.04, r107 Please provide any additional information below. This bug is also causing incorrect results in the mandelbrot 2.2 sdk\r\nexample without manual rolling of loop bodies.  We need a simple test case\r\nto reproduce this before we can start diagnosing the problem in detail.  It\r\nis not obvious from examining the dataflow traces from either example.\n\n_Original issue: http://code.google.com/p/gpuocelot/issues/detail?id=20_"},"comment":{"url":"https://api.github.com/repos/gtcasl/gpuocelot/issues/comments/87338386","html_url":"https://github.com/gtcasl/gpuocelot/issues/19#issuecomment-87338386","issue_url":"https://api.github.com/repos/gtcasl/gpuocelot/issues/19","id":87338386,"user":{"login":"jwang323","id":11183505,"avatar_url":"https://avatars.githubusercontent.com/u/11183505?v=3","gravatar_id":"","url":"https://api.github.com/users/jwang323","html_url":"https://github.com/jwang323","followers_url":"https://api.github.com/users/jwang323/followers","following_url":"https://api.github.com/users/jwang323/following{/other_user}","gists_url":"https://api.github.com/users/jwang323/gists{/gist_id}","starred_url":"https://api.github.com/users/jwang323/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jwang323/subscriptions","organizations_url":"https://api.github.com/users/jwang323/orgs","repos_url":"https://api.github.com/users/jwang323/repos","events_url":"https://api.github.com/users/jwang323/events{/privacy}","received_events_url":"https://api.github.com/users/jwang323/received_events","type":"User","site_admin":false},"created_at":"2015-03-29T01:32:44Z","updated_at":"2015-03-29T01:32:44Z","body":"_From [gregory....@gatech.edu](https://code.google.com/u/108429927188929695221/) on August 15, 2009 18:15:30_\n\nr108 adds a fix to the version of mri-fhd in ocelot."}}
