Sema::InstantiateClass should check only exception specs added during class instantiation and ignore already present delayed specs. This fixes a case where we instantiate a class before parsing member initializers, check exceptions for a different class and fail to find a member initializer. Which is required for comparing exception specs for explicitly-defaulted and implicit default constructor. With the fix we are still checking exception specs but only after member initializers are present. Removing errors in crash-unparsed-exception.cpp is acceptable according to discussion in PR24000 because other compilers accept code in crash-unparsed-exception.cpp as valid. rdar://problem/34167492 Reviewers: davide, rsmith Reviewed By: rsmith Subscribers: dim, cfe-commits Differential Revision: https://reviews.llvm.org/D37881 llvm-svn: 313906
