This causes acrash when the following conditions are met: - a CXXRecordDecl is invalid, - it is provided via ExternalASTSource (e.g. from PCH), - it has inherited constructors (they create ShadowDecls), - lookup of its constructors was not run before ASTWriter serialized it.This may require the ShadowDecls created for inherited constructors tobe removed from the class, but that's no longer possible since class isprovided by ExternalASTSource.See provided lit test for an example.Reviewers: bkramerReviewed By: bkramerSubscribers: cfe-commitsDifferential Revision: https://reviews.llvm.org/D42810llvm-svn: 324062 List of files: /llvm-project-15.0.7/clang/test/Index/crash-preamble-classes.cpp Fri, 02 Feb 2018 08:40:08 +0000 Ilya Biryukov <ibiryukov@google.com>
