When trying to use the new threads functionality in C++11 the program crashes
with the following error:

terminate called after throwing an instance of 'std::system_error'
terminate called recursively

Fatal signal received: Aborted

Stack backtrace:

The program that produced the error was:

#include <thread>
#include "stdio.h"

void test()
{
printf("Hello from test\n");
}

int main(int argc, char *argv[])
{
std::thread t(test);
t.join();
return 0;
}

It was compiled with the cross compiler built from trunk on 27th May 2014 on
Cygwin and tried again with the same build on Debian.

~/gccsdk/cross/bin/arm-unknown-riscos-g++ -std=c++11 -static main.cc
