Summary: ICE on non-valid code with emplace_back
Classification: Unclassified
Product: gcc
Version: 4.7.3
Status: UNCONFIRMED
Severity: normal

Preprocessed file g++ is asking me to give
The following code produces an internal compiler error.
The code is so simple that I am surprised I did not find a bug report for it.
====== Code ======
#include <vector>
struct Sums {
int pos;
};
int main() {
std::vector<Sums> sums;
sums.emplace_back(1);
}
====== g++ output ======
$ g++ -std=c++11 -v 345.cpp
Using built-in specs.
