I ran the test & understand it a bit better now - so the abort is part of the code, when the test fails, the test harness uses abort to fail. So this isn't "clang causes abort" (it didn't select a bad instruction, etc) this is "clang causes test failure" - this could be any number of things in ter

Re: [cfe-users] How to determine if variable is templated?

as I mentioned in the link previously - "getTemplateSpecializationKind" on the VarDecl should tell you if it's a template at all. At least I think that's how you'd go about it... - Dave On Sun, Feb 20, 2020 at 4:08 PM Robert Ankeney via cfe-users < cfe-users@lists.llvm

Hi, It looks like the working of C++20 introduced some breaking compatibilities with some C++17 accepted patterns. From what I read in https://reviews.llvm.org/rL375306 these incompatibilities weren’t really intented by the initial C++20 proposal, and thus broken patterns were still allowed as
