Description Sami Liedes 2014-12-18 16:25:56 PST 
Fuzzing discovered that the test case below, when given as input to

  clang -fno-crash-diagnostics -std=c++11 -xc++ -c -emit-llvm

causes this assertion failure:

clang-3.6: /home/sliedes/projects/llvm/llvm.src/tools/clang/include/clang/AST/TypeNodes.def:86: clang::TypeInfo clang::ASTContext::getTypeInfoImpl(const clang::Type*) const: Assertion `!T->isDependentType() && "should not see dependent types here"' failed.

Test case:

--------------------------------------------------
struct {__typeof Di r} S[1
