Yes and no...

Include this .cc file in a project.

// foo.cc
// Fixes the new handler "bug".

#include <new>

void __my_new_handler (void) {
  throw bad_alloc();
}

class __dummy_class {
  __dummy_class (void) { set_new_handler(__may_new_handler); }
};

__dummy_class __dummy_object; // This will construct at startup, and the
                                                            // constructor will
set the new handler.


In another module, such as the one with main, #include this:

// foo.h

extern __dummy_class __dummy_object;  // Force linker to link the foo.o.
