Created attachment 13485 [details] test case Fuzzing discovered that the attached test case, when given as input to clang -fno-crash-diagnostics -std=c++11 -xc++ -c -emit-llvm causes this assertion failure: clang-3.6: tools/clang/lib/Parse/ParseCXXInlineMethods.cpp:359: void clang::Parser::ParseLexedMethodDeclaration(clang::Parser::LateParsedMethodDeclaration &): Assertion `!PP.getSourceManager().isBeforeInTranslationUnit(origLoc, Tok.getLocation()) && "ParseAssignmentExpression went over the default arg tokens!"' failed.
The failing assertion had been removed in r225763. The test case seems ok with current trunk.
