C++ code (such as std::queue<>) won't throw any exceptions if c++ exception is set to not supported (default setting)

There is a compiling option --exception which enables C++ exception handling. By default it is not supported.

According to C++ standard, std::queue<>::push might throw exceptions if memory allocation fails. So if exception is not supported, what is the behaviour when an exception should be thrown?

Essentially, nothing happens and the program continues. If a bad_alloc exception should be thrown, the allocation routine will instead return a NULL pointer, which may mean that the library will write on uninitialized memory. If there's a possibility that an exception may happen, you need to compile with --exceptions to get the standard C++ behavior.
