           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal

Hello!

When I try to compile the following program

#include <bitset>
std::bitset<2147483648> b;
int main() {}

cc1plus tries to eat all available memory and hangs.

Compilation command is g++ -o test test.cpp -std=c++11

When I use -std=c++98, everything works fine.
