Mac OS 上 Valgrind 下的 std::thread.join() SIGSEGV

以下简单代码（C++ 11）将在 Mac OS 和 Linux 上运行：

#include <thread>
#include <chrono>
#include <iostream>

void threadFunction() {
    for (int cc=0; cc < 10000000; ++cc) {
        if (cc%1000000 == 0) {
            std::this_thread::sleep_for(std::chrono::milliseconds(200));
        }
    }
}


int main(int argc, char **argv) {
    std::thread threads[10];
    for (int tt = 0; tt < 10; ++tt) {
        threads[tt] = std::thread(threadFunction);
    }
    // Wait for the threads to complete
    for (int tt = 0; tt < 10; ++tt) {
        printf("About to join %d\n", tt);
        std::cout.flush();
        threads[tt].join();
        printf("Joined %d\n", tt);
        std::cout.flush();
    }
    return 0;
}

然而，在 Valgrind 中包装执行：

valgrind --leak-check=full --show-reachable=no --track-fds=yes --error-exitcode=1 --track-origins=yes ./theexecutable

...现在它可以在 Linux 上运行，但不能在 Mac OSX 上运行，失败并显示：

==47544== Process terminating with default action of signal 11 (SIGSEGV)
==47544==  Access not within mapped region at address 0x700008F31C3E

==47544==    by 0x100001BB1: main (in ./vgtest)

任何想法为什么会失败（然后仅在 OSX 上）？

Valgrind-3.11.0，OSX 10.11.3

这是 Valgrind 中的一个错误。主要错误报告可以在这里找到：https://bugs.kde.org/show_bug.cgi?id=349128
