boost.thread-简单示例中的访问冲突

Question

I'm just trying to run a very simple example of using threads with boost . Here is the code:

#include <iostream>
#include <boost/thread.hpp>

void workerFunc()
{
    std::cout << "hi" << std::endl;
}

int main(int argc, char* argv[])
{
    boost::thread workerThread(workerFunc);
    workerThread.join();
    return 0;
}

But I get an exception:

(boost_thread-vc140-mt-1_59.dll) in test.exe: 0xC0000005: Access violation reading location 0x0000000000000019.

Despite the exception, the program works and I can see hi in console. I use VS2015, x64 configuration. Where is my mistake?

Answer 1

There's clearly undefined behaviour, as there's nothing wrong with the code.

So, what is wrong?

There's likely an error in the build configuration, deployment (runtime environment), or a mismatch between those two.

Specifically:

• you might build your project with a compiler version/flags that make it binary incompatible with the libraries used.
• you might link to the import libraries of 1 build/version of boost and be finding a different version at runtime

Both conditions introduce Undefined Behaviour . Anything can happen.
