It also fails on a 2009 Nehalem quad core with a 5770, now running OSX server.
So to be clear, does anyone on the list have an ATI card either the generation or prior ( i.e. ATI 5870,5770, 4870, 4770) with a modern Nehalem (4 core) or Westmere (6 core) intel processor that can do OpenCL work? Is there a concise test case that can be used to test this? -- Glen GNU gdb 6.3.50-20050815 (Apple version gdb-1518) (Thu Jan 27 08:34:47 UTC 2011) Copyright 2004 Free Software Foundation, Inc.
