> myfun2(const int)
Top-level const is removed from function parameters, so this function is
equivalent to:
void myfun2(int);
And the instantiation wrapper<const int> is equivalent to:
template<> void wrapper<const int>(void (*)(int), int);
G++ gets confused trying to match const int to int somewhere.
f.cc: In function ‘void test()’:
f.cc:31:33: error: no matching function for call to ‘wrapper(void (&)(int),
const int&)’
wrapper<const int>(myfun2, b);
^
f.cc:31:33: note: candidate is:
f.cc:4:1: note: template<class ... Args> void wrapper(void (*)(Args ...), Args
...)
wrapper(void (*f)(Args...),
^
f.cc:4:1: note: template argument deduction/substitution failed:
f.cc:31:33: note: mismatched types ‘const int’ and ‘int’
wrapper<const int>(myfun2, b);
^
