@lebedev.ri Thanks for responding! I didn't intend to mail it just yet before narrowing the problem down, and realized too late just saving the revision would add the subscribers. I'll get back once I'll be able to pinpoint the problem better, it's entirely possible that your commit exposes the bug either in llvm->ptx translation (then I would be able to fix it) or the ptx emitted triggers a ptxas bug with gives bad ptx->SASS lowering.
