Precisely why (i.e. backend) a source file with an empty main function
instantiating nothing should never, *ever*, ICE a compiler. I mean, I'd
get why a frontend might ICE. But if you don't instantiate anything
apart from an empty main function, then the backend ought to not be
doing anything. Ever.

I'll get to submitting a repro sometime between tomorrow and Wednesday,
depending on workload. Outcome review takes precedence.

Thanks for the quick reply Stephan, and apologies for the ribbing. I
recently ran clang-tidy on AFIO which is only a three year old codebase,
and I was fairly shocked at how awful - as in, clearly hard "segfault me
now" UB - the code I had written. It happens to us all. (And well done
on whomever added to clang-tidy the "you are copy slicing an object with
multiple inheritance" lint check)

Niall
