std::terminate

Defined in header <exception> 
void terminate();
 (until C++11) 
[[noreturn]] void terminate();
 (since C++11)

std::terminate() is called by the C++ runtime when exception handling fails for any of the following reasons:

1) an exception is thrown and not caught (it is implementation-defined whether any stack unwinding is done in this case)
2) an exception is thrown during exception handling (e.g. from a destructor of some local object, or from a function that had to be called during exception handling)
3) the constructor or the destructor of a static or thread-local object throws an exception
4) a function registered with std::atexit or std::at_quick_exit throws an exception
5) a noexcept specification is violated (it is implementation-defined whether any stack unwinding is done in this case)
6) a dynamic exception specification is violated and the default handler for std::unexpected is executed
7) a non-default handler for std::unexpected throws an exception that violates the previously violated dynamic exception specification, if the specification does not include std::bad_exception
8) std::nested_exception::rethrow_nested is called for an object that isn't holding a captured exception
9) an exception is thrown from the initial function of std::thread
10) a joinable std::thread is destroyed or assigned to

std::terminate() may also be called directly from the program.


In any case, std::terminate calls the currently installed std::terminate_handler. The default std::terminate_handler calls std::abort.

If a destructor reset the terminate handler during stack unwinding and the unwinding later led to terminate being called, the handler that was installed at the end of the throw expression is the one that will be called. (note: it was ambiguous whether re-throwing applied the new handlers).

 (until C++11)

If a destructor reset the terminate handler during stack unwinding, it is unspecified which handler is called if the unwinding later led to terminate being called.

 (since C++17)
