This is not adhering to the ISO standard. gcc 2.95.x didn't do that. It correctly returns 0 when nothing is available etc. >How-To-Repeat: #include <iostream> using namespace std; int main() { // This call blocks, which it shouldn't. cout << cin.rdbuf()->in_avail() << endl; } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
