thread_local vector segmentation fault at end of program in C++ - c++

Question

I'm trying to make a multi-threaded program but am having a weird problem with thread local vectors. Here's the (stripped-down to only have the error) code:
#include <vector>
#include <iostream>
thread_local std::vector<int> vec;
int main(){
vec.push_back(3);
std::cout << vec[0];
// Make you push enter to show the error is at the end
std::cin.ignore();
}
The program compiles fine and runs mostly fine, but after I press enter I get a "program has stopped working" message. I ran it in gdb and got this error:
Program received signal SIGSEGV, Segmentation fault.
0x004030b0 in std::vector<int, std::allocator<int> >::~vector() ()
Somehow, there's an error in the vector's destructor. Going through it with a breakpoint shows that this error happens as the program is quitting.
Making the vector not thread local makes the program work, but of course I need it to be thread local. If I don't interact with the vector at all, the program works fine.
I'm thinking I'll have to use some alternative, but does anybody know a way to make this work? Thanks!
EDIT: I'm stupid and forgot more info on my system. I'm using Windows Vista 64-bit. Running g++ -v gives me:

COLLECT_GCC=g++
COLLECT_LTO_WRAPPER=C:/MinGW/bin/../libexec/gcc/i686-w64-mingw32/5.2.0/lto-wrapper.exe

Configured with [edited out because it's too big and probably not relevant]
Thread model: posix
gcc version 5.2.0 (i686-posix-dwarf-rev0, Built by MinGW-W64 project)
The thread model might actually have a lot to do with it.

It is setup dependent; I have successfully compiled and run your example program on Windows 7 (64 bit) with the 64 bit MinGW. Perhaps it is related to the fact that you use the 32 bit MinGW installation on 64 bit platform? My g++ -v gives the following (same version and thread model as yours, different arch):
