Bug #: 51265
Summary: internal compiler error: in finish_decltype_type, at
cp/semantics.c:5244
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: i.nixman@gmail.com
When I try to compile following code, I get error:
test1.cpp: In instantiation of 'void xx(T*, A ...) [with X = int
(Funny::*)(int) const; X ff = &Funny::print3; R = int; T = Funny; A = {int}]':
test1.cpp:35:74: required from here
test1.cpp:23:9: internal compiler error: in finish_decltype_type, at
cp/semantics.c:5244
code:
#include <iostream>
struct Funny {
void print(int i) {
std::cout << "void (Funny::*)(int): " << i << std::endl;
}
int print2(int i) {
std::cout << "int (Funny::*)(int): " << i << std::endl;
return i;
}
int print3(int i) const {
std::cout << "int (Funny::*)(int) const: " << i << std::endl;
return i;
}
};
template<typename T, typename X, X ff>
void c(){ T abc; (abc.*ff)(123); }
template<typename X, X ff, typename R, typename T, typename... A >
void xx(T* _obj, A... args){
for (int i : {2,4}) std::cout << i << std::endl; // #3 int i is OK
{
/* 23 */ c<T, decltype(ff), ff>(); // #1 summary error trigger here
}
std::cout << "xx()" << std::endl;
(_obj->*(ff))(args...);
// #2 can not define any object here, even int
// T abc;
//(abc.*ff)(args...);
}
int main()
{
Funny abc;
/* 35 */ xx<int (Funny::*)(int)const, &Funny::print3, int, Funny, int>(&abc,
3);
return 0;
}

Can be reduced to this, and seems a Regression:
struct Funny
{
int print3(int) const;
};
template<typename X, X ff>
void c();
template<typename X, X ff, typename R, typename... A>
void xx(A... args)
{
c<decltype(ff), ff>();
}
int main()
{
xx<int (Funny::*)(int) const, &Funny::print3, int, int>(3);
}

On it. A tad simpler:
struct Funny
{
int print(int);
};
template<typename X, X ff>
void c();
template<typename X, X ff>
void xx()
{
c<decltype(ff), ff>();
}
int main()
{
xx<int (Funny::*)(int), &Funny::print>();
}

Even:
struct Funny;
template<typename X>
void c();
template<typename X>
void xx()
{
c<decltype(ff)>();
}
int main()
{
xx<int(Funny::*)(int)>();
}
