We came across a Clang ICE on malformed input while reducing the test-case of
a separate problem.
This ICE does not appear to be a regression.
I can reproduced this ICE since SVN revision 240000.
Here is the test
$ cat t.cpp
template<class Alpha,
class Bravo,
class Charlie
: public Delta<Alpha, Bravo, Echo>
: Delta<Alpha, Bravo, Echo>(Foxtrot(Golf), Hotel)
{
explicit Charlie(const India& _Str, size_t Hotel = 0)
{
Here are the relevant error messages from the crash dump
$ clang++ -c t.cpp
clang-4.0: /home/chli/Source/usvn/llvm/tools/clang/lib/Sema/SemaInit.cpp:6296:
clang::ExprResult clang::InitializationSequence::Perform(clang::Sema&, const
clang::InitializedEntity&, const clang::InitializationKind&,
clang::MultiExprArg, clang::QualType*):
Assertion `Kind.getKind() == InitializationKind::IK_Copy ||
Kind.isExplicitCast() || Kind.getKind() == InitializationKind::IK_DirectList'
failed.

Stack dump:
1. t.cpp:8:5: current parser token '{'
2. t.cpp:3:2: parsing struct/union/class body 'Charlie'
