>Description:
	
iostreams in the new libstc++ ignore out of space errors, no exception or
error flags are set.
>How-To-Repeat:
	
nospacetest.cpp:
#include <fstream>
#include <iostream>
using namespace std;
int main(void) {
	ofstream foo("foo.bar");
	foo << "hellohellohellohello\n";
	cout << foo.good() <<" "<< foo.eof() <<" "<< foo.fail() <<" "<< foo.bad() <<"\n";
	foo.close();
	cout << foo.good() <<" "<< foo.eof() <<" "<< foo.fail() <<" "<< foo.bad() <<"\n";
	return 0;
}

mount -t tmpfs tmpfs /mnt -o remount,defaults,size=0k,nr_inodes=1k
cd /mnt
nospacetest
1 0 0 0
1 0 0 0

output when compiled with gcc 2.95:
1 0 0 0
0 0 2 0
