[Bug 26914] New: setvbuf() breaks iostream input (msvcrt/msvcp)

http://bugs.winehq.org/show_bug.cgi?id=26914

           Summary: setvbuf() breaks iostream input (msvcrt/msvcp)
           Product: Wine
           Version: 1.3.17
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: UncombedCoconut(a)gmail.com


This bug affects Stockfish, a chess engine. I've made a simplified test case.

This C++ program copies a line from stdin to stdout, or complains on EOF.
It works on WinXP, but under Wine 1.2.2 or 1.3.17 it says "No input". (You do
have to type a line before it will terminate.)

Here's the code and build command. The exe is attached.
$ cat setvbuf-test.cpp 
#include <iostream>
#include <cstdio>
#include <string>

int main() {
    std::string input;
    setvbuf(stdin,NULL,_IONBF,0);
    setvbuf(stdout,NULL,_IONBF,0);
    if (std::getline(std::cin, input))
        std::cout << "Input was: " << input << "\n";
    else
        std::cout << "No input\n";

    return 0;
}

$ i686-w64-mingw32-g++ -o setvbuf-test.exe -static-libgcc setvbuf-test.cpp
