<p>Hi Vincent, in isStdioDescriptorATTY at line 898 there is no guard to check if pGetFileInformationByHandleEx has already been fetched.  The code needs to be something like</p>
<pre><code>static pfnGetFileInformationByHandleEx pGetFileInformationByHandleEx = NULL;

if (! pGetFileInformationByHandleEx) {
        pGetFileInformationByHandleEx = (pfnGetFileInformationByHandleEx)
                GetProcAddress(GetModuleHandle(TEXT("kernel32.dll")),
                                        "GetFileInformationByHandleEx");
        if (pGetFileInformationByHandleEx == NULL)  return -2;
}
</code></pre>
