Author: jonastoth Date: Mon Jan 21 05:26:18 2019 New Revision: 351743 URL: http://llvm.org/viewvc/llvm-project?rev=351743&view=rev Log: [clang] add tests to ExprMutAnalyzer that reproduced a crash in ASTMatchers
Summary: This patch adds two unit-tests that are the result of reducing a crashing TU when running ExprMutAnalyzer over it. They are added only to ensure the regression that has been fixed with https://reviews.llvm.org/D56444 don't creep back.
