Comment 1 Wade Walker 2014-03-02 16:51:43 CET 
Bought a used Radeon HD 5450 at a thrift shop yesterday, will try to duplicate these at home and debug.
Comment 2 Wade Walker 2014-03-08 17:17:49 CET 
Duplicated these errors on Win 8.1 with Radeon HD 5450, debugging now.
Comment 3 Wade Walker 2014-03-08 23:13:41 CET 
programBinariesTest() failure was due to AMD drivers crashing in clCreateKernelsInProgram() when the program is not built yet, instead of returning error code CL_INVALID_PROGRAM_EXECUTABLE as they should.

lowLevelVectorAddTest() failure was apparently due to the AMD drivers writing past the end of a direct byte buffer in such a way that it made System.gc() crash when called during teardown (this crash didn't even dump stack). Making the buffer larger solved the problem.
Comment 4 Wade Walker 2014-03-08 23:42:31 CET 
Fixes are at https://github.com/WadeWalker/jocl/tree/bug_989_fix_AMD_driver_crashes, waiting to merge until build server is back up
Comment 5 Wade Walker 2014-04-13 23:10:14 CEST 
lowLevelVectorAddTest() still fails on linux-x86_64-amd and win7-x86_32-amd; will try increasing buffer size further and rewinding it between all reuses.
Comment 6 Wade Walker 2014-04-13 23:29:53 CEST 
That fixed it.
