Summary: Assertion failure in clang++ in gnu++0x mode
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal

Output from compiling, including assertion failure and backtrace
The following (invalid) code triggers an assertion failure in clang++.
The assertion is "SemaCXXCast.cpp:612: TryCastResult
TryStaticCast(clang::Sema&, clang::Expr*&, clang::QualType, bool, const
clang::SourceRange&, unsigned int&, clang::CastKind&, clang::CXXCastPath&):
Assertion `SrcType->getAs<EnumType>()->getDecl()->isScoped()' failed."; full
output in the attachment.
The source code has been reduced with multidelta, so looks a bit odd.
