Comment (by pulkomandy):
With gcc4.8, the support for this was enabled. Compile with:
{{{
g++-x86 --std=c++11
}}}
The resulting binary raises an exception, however (
gcc_x86-4.8.2_2014_01_28-2-x86_gcc2.hpkg / hrev46961).
Here is another test case:
{{{
#include <thread>
#include <stdio.h>
int main(void)
{
std::thread::id t1 = std::thread::id();
std::thread::id t2 = std::thread::id();
printf("%s\n", t1 == t2 ? "PASS" : "FAIL");
}
}}}
According to
http://en.cppreference.com/w/cpp/thread/thread/id/operator_cmp, operator==
should return true when comparing two uninitialized thread ids.
