I guess you are using egcs 1.0.2.  For egcs 1.0.x, the behavior when new
cannot allocate memory is displaying memory exhaust error and abort. 
For latest egcs snapshot, bad_alloc is thrown.

With egcs 1.0.x, you can get the desired behavior by using
set_new_handler and throwing an exception inside your new handler. 
However it does not always work as exception handling code needs some
free memory to operate which is also true for the latest egcs snapshot.
