What does the following runtime error mean: “terminate called without an active exception\n Aborted”

Question

The bug disturbed me about two days: when running the code I have a runtime error of \"terminate called without an active exception\\n Aborted\",why?

I try to locate the

Like Gearoid Murphy said the error happens when the thread object is destructed before the thread function itself has been fully executed. I detected this error using tinythread library (http://tinythreadpp.bitsnbites.eu/):

Before:

#include "tinythread.h"
...
void fork_thread(void (*function_pointer)(void * arg), void * arg_pointer) {
    tthread::thread t(function_pointer, arg_pointer);
    // t is destructed here, causing the "terminate called ..." error
}

After:

#include "tinythread.h"
...
void fork_thread(void (*function_pointer)(void * arg), void * arg_pointer) {
    tthread::thread * t = new tthread::thread(function_pointer, arg_pointer);
    // now the new thread object is not destructed here, preventing
    // the "terminate called ..." error. Remember that because thread
    // object must now be destructed explicitly (i.e. manually) with delete
    // call you should store the pointer t to a vector of thread pointers
    // for example.
}
