Severity: important
For some reason, files that don't exist are not reported as
bad in something like
ifstream file("my crap file that does not exist");
file.bad(); <== returns false!
I've attached a test program that demonstrates it. It is
related to the problem in Aria

I'm closing this bug since it is apparently the correct behaviour
of stdc++. Apparently if a contructon fails to open, it doesn't
mean that bad() is true... Blah....
