new and exceptions

I am using egcs 1.0.2 under cygwin32. In g++, does new throw a bad_alloc
exception if the underlying alloc fails. The following code should eventually
generate such an exception (if iterated enough times).
try {
int * x = new int[50000000];
}
catch (bad_alloc a)
{
cout << "bad_alloc caught";
abort(1);
}
Instead of generating the "caught" message, we get the following error
message
(EXECUTABLE_NAME) commit_and_ind: VirtualAlloc failed
Virtual memory exceded in `new'
An earlier test of exceptions (explicitly throwing one) worked fine.
Any help would be appreciated.
