The code is:

#define _GLIBCXX_DEBUG

#include <set>
#include <map>

using namespace std;

map<int, pair<bool, pair<int,int> > > q;

int main(int argc, char* argv[])
{
    set<int> can;
    can.insert(1);
}

This bug was also reported to TDM-GCC's bugtracker at
http://sourceforge.net/p/tdm-gcc/bugs/264/

Smaller example:

#define _GLIBCXX_DEBUG
#include <set>

std::set<int> a;

int main() {
    std::set<int> b;
}

This report is not very useful without a stack trace showing where the
exception is thrown. I suspect it's a mingw-w64 problem as it doesn't happen on
other targets, so there may be nothing to fix in the upstream libstdc++ code.

As requested at https://gcc.gnu.org/bugs/ please provide the output of 'gcc -v'
not just the version number.
