Backtrace
I receive an internal compiler error with Clang 3.4.2. I attach the backtrace,
run script, and preprocessed source code. The first few lines of the backtrace
are:
```
clang:
/home/eschnett/SIMFACTORY/llvm-3.4.2/src/llvm-3.4.2.src/tools/clang/lib/Sema/SemaTemplate.cpp:5121:
clang::ExprResult clang::Sema::BuildExpressionFromDeclTemplateArgument(const
clang::TemplateArgument&, clang::QualType, clang::SourceLocation): Assertion
`!RefExpr.isInvalid() && Context.hasSameType(((Expr*)
RefExpr.get())->getType(), ParamType.getUnqualifiedType())' failed.
clang::Sema::DeduceTemplateArguments(clang::ClassTemplatePartialSpecializationDecl*,
clang::TemplateArgumentList const&, clang::sema::TemplateDeductionInfo&) + 788
12 clang 0x0000000000d6cc94
clang::Sema::InstantiateClassTemplateSpecialization(clang::SourceLocation,
clang::ClassTemplateSpecializationDecl*, clang::TemplateSpecializationKind,
bool) + 676
13 clang 0x0000000000d970c6
clang::Sema::RequireCompleteTypeImpl(clang::SourceLocation, clang::QualType,
clang::Sema::TypeDiagnoser&) + 1414
```
This occurs on Linux. I built Clang 3.4.2 myself, using GCC 4.9.0. I am also
building against GCC 4.9.0's libstdc++ when the error occurs.</pre>
