           Summary: Calling condition variable's notify_all() causes
                    SEGFAULT when the binary is statically linked
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++

Example code causing segmentation fault

The following code causes segmentation fault on Debian Linux (Sid) WHEN THE
BINARY IS STATICALLY LINKED. Code works correctly when the binary is linked
dynamically:

#include <condition_variable>

int main()
{
  std::condition_variable cv;
  cv.notify_all();
  return 0;
}

Commands:

g++ -v -save-temps -std=c++11 -static test.cpp
./a.out
Segmentation fault

uname -a
Linux moria 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3 (2015-04-23) x86_64
GNU/Linux

gcc -v
gcc version 4.9.2 (Debian 4.9.2-10)

Tested with 5.1.1 and it creates Segmentation fault.
