sammccall added a comment.
We're seeing new clang crashes that bisect to this commit, with modules only.
I have it mostly-reduced and will post shortly, trying to see if I can simplify
any further (since modules reproducers are a pain).
Meanwhile, the assert/stack in case it's already useful:
assertion failed at
third_party/llvm/llvm-project/clang/lib/Sema/SemaTemplateInstantiate.cpp:4065
in llvm::PointerUnion<Decl *, LocalInstantiationScope::DeclArgumentPack *>
*clang::LocalInstantiationScope::findInstantiationOf(const Decl *):
isa<LabelDecl>(D) && "declaration not instantiated in this scope"
