Oops, it seems like i didn't leave a message properly.
tbbmalloc's operator new and operator new[] overloads in src/tbbmalloc/proxy.cpp go straight to throwing std::bad_alloc if scalable_msize(sz) returns NULL. I have installed a new_handler using std::set_new_handler(handler), and I expect this handler to be called in the new operator when tbbmalloc has run out of memory.
This is an enhancement request for future versions of tbbmalloc.
