Extended Description

During the compilation of the following Code clash 8.0 crashes: #include

template<typename type, typename unitenum, unitenum DefaultUnit> class CommonUnit { public: typedef unitenum eUnit; typedef type DataType;

template inline void set(settype Value = 0, unitenum theUnit = DefaultUnit) { m_Value = static_cast(Value * static_cast(theUnit)); }

private: type m_Value;

};

enum eSpeedUnit { CentimetersPerSecond = 1, };

typedef CommonUnit<int32_t, eSpeedUnit, CentimetersPerSecond> Speed;

template<> template inline void Speed::set(settype Value, eSpeedUnit theUnit) { }

int main(void) { Speed s; s.set(1); }

This still triggers an assertion on post 16 trunk(c3b27c236d6a495acbe2ba95c43faf9a98e81a46)

https://godbolt.org/z/16EGfT7cM

The slightly shorted code is


template<typename type, typename unitenum, unitenum DefaultUnit>
class CommonUnit
{
public:

   template<typename settype>
   inline void set(settype Value, unitenum theUnit = DefaultUnit)
   {
      static_cast<type>(Value * static_cast<settype>(theUnit));
   }
};

enum eSpeedUnit
{
   CentimetersPerSecond = 1,
};

typedef CommonUnit<int, eSpeedUnit, CentimetersPerSecond> Speed;

template<>
template<typename settype>
inline void Speed::set(settype Value, eSpeedUnit theUnit)
{
}

int main(void)
{
    Speed s;
    s.set(1);
}

The assertion is

clang++: /root/llvm-project/clang/lib/CodeGen/CGCall.cpp:4402: void clang::CodeGen::CodeGenFunction::EmitCallArgs(clang::CodeGen::CallArgList&, 
clang::CodeGen::CodeGenFunction::PrototypeWrapper, llvm::iterator_range<clang::Stmt::CastIterator<clang::Expr, const 
clang::Expr* const, const clang::Stmt* const> >, clang::CodeGen::CodeGenFunction::AbstractCallee, unsigned int, 
clang::CodeGen::CodeGenFunction::EvaluationOrder): 
Assertion `(isGenericMethod || Ty->isVariablyModifiedType() || Ty.getNonReferenceType()->isObjCRetainableType() ||
       getContext() .getCanonicalType(Ty.getNonReferenceType()) .getTypePtr() == 
       getContext().getCanonicalType((*Arg)->getType()).getTypePtr()) 
&& "type mismatch in call argument!"' failed.

The full backtrace is

clang++: /root/llvm-project/clang/lib/CodeGen/CGCall.cpp:4402: void clang::CodeGen::CodeGenFunction::EmitCallArgs(clang::CodeGen::CallArgList&, clang::CodeGen::CodeGenFunction::PrototypeWrapper, llvm::iterator_range<clang::Stmt::CastIterator<clang::Expr, const clang::Expr* const, const clang::Stmt* const> >, clang::CodeGen::CodeGenFunction::AbstractCallee, unsigned int, clang::CodeGen::CodeGenFunction::EvaluationOrder): Assertion `(isGenericMethod || Ty->isVariablyModifiedType() || Ty.getNonReferenceType()->isObjCRetainableType() || getContext() .getCanonicalType(Ty.getNonReferenceType()) .getTypePtr() == getContext().getCanonicalType((*Arg)->getType()).getTypePtr()) && "type mismatch in call argument!"' failed.
