Created attachment 94093 [details] crashing again with patch from #8 (In reply to comment #8) > Created attachment 94078 [details] > Patch to test > > Can you test this patch and post the output of R600_DEBUG=cs It's crashing again with 0x7f76ed4687c0: i32 = ExternalSymbol'__muldi3' For some reason the output seems to be doubled in my log.
