I don't know these parts of C++ very well, but maybe an easy fix, 
addressing this once and for all, would be doing the equivalent of 
"set_new_handler (gcc_unreachable)" (or maybe a wrapper around fatal 
("out of memory")?) at some point during gcc's initialization?  This 
should have the desired effect, shouldn't it?
