Well, I suppose you could test it yourself... it's not exactly a major
bit of programming.

However, I decided to try it out of personal curiosity.  Here are my
results:

#include <iostream.h>

int main( void )
{
    char *c;
    c = new char[1024*1024*1024];
    delete[] c;
    return 0;
}

[WIN] D:\TEMP>new
Virtual memory exceeded in `new'

According to my C++ textbook, you can #include a special header file
that defines a version of new that supports exceptions.
