I have ran into a problem compiling some template code with Visual Stuido 2010 SP1, cl.exe version 16.0.40219.1
The following code will cause the compiler to access violate:
template<typename T>
class A
{
A(){}
};
template<typename T>
class B : public A<T>
{
using A::A(); // Compiler access violates
// **EDIT**
//using A<T>::A<T>; // Compiler succeeds
//using A<T>::A(); // Compiler reports error
};
int main(int argc, char* argv[])
{
return 0;
}
It generates the following error (in addition to the "cl.exe has stopped working, C0000005 exception):
1>d:\projects\cpptest\cpptest\cpptest.cpp(11): fatal error C1001: An internal error has occurred in the compiler.
1> (compiler file 'msc1.cpp', line 1420)
1> To work around this problem, try simplifying or changing the program near the locations listed above.
The code compiles fine (well, that is, it emits a proper error message and doesn't crash the compiler) in Dev-C++ with g++.
main.cpp:11: error: `template<class T> class A' used without template parameters
main.cpp:11: error: expected nested-name-specifier before "A"
main.cpp:11: error: using-declaration for non-member at class scope
main.cpp:11: error: expected `;' before '(' token
main.cpp:11: error: expected unqualified-id before ')' token
make.exe: *** [main.o] Error 1
EDIT The following, however, compiles fine, without access violation, so it seems this is related to templates:
class A
{
A(){}
};
class B : public A
{
using A::A;
};
int main(int argc, char* argv[])
{
return 0;
}
Do you think this is worth reporting to Microsoft? Can anyone else reproduce this? Maybe try in Visual Studio 2013 to see if it still occurs?
