GCC 4.7 (revision 177825) triggers a segmentation fault when compiling the
following source code.
#include <fstream>
int main()
{
std::make_pair<int, std::ofstream>(int(), std::ofstream());
}
Call to g++ including version, segfault at the end of the output:
% LANG=C g++ -std=c++0x -save-temps -O0 -v crash.cpp
Using built-in specs.
