>>>> Could you include the source code for the test? (& if it's the same source as in the bug - that one's a bit long, hopefully it can be further reduced - usually it's possible/safe to remove templates, for example). I can try to help with the reduction if you like.

>>> I can't seem to reproduce it with that source and the command line from one of the crash dumps listed earlier in the bug (after reverting your patch locally) - what was the -cc1 command line you used along with that source?

>>> This was the best that creduce could come up with after I helped it a little by rewriting the input. I admit that didn’t try very hard to specialize the templates. I then compiled the code to IR and ran bugpoint on it. I opted to not include the sources because they were a bit long. I mean, ideally, this whole testcase will fail at some point in the future, when DbgValueHistoryCalculator becomes smarter. Unfortunately we don’t have a textual representation for MachineInstructions, which is what we would really need here to turn this into a useful testcase. Otherwise we have to play games to trick the backend to do the exact sequence of spilling/rematerialization necessary to trigger a certain behavior, which IMO isn’t really worth the effort.
