Bug 19240 – WinLauncher _tWinMain() returns uninitialized memory.

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Paul Pedriana]

WinLauncher _tWinMain() returns uninitialized memory for the msg.wParam variable in some cases. The problem is that the msg variable is uninitialized. The following shows the relevant code:

int APIENTRY _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)
{
    .
    .
    MSG msg;
    .
    .
    HRESULT hr = CoCreateInstance(CLSID_WebView, 0, CLSCTX_ALL, IID_IWebView, (void**)&gWebView);
    if (FAILED(hr))
        goto exit;
    .
    .
exit:
    .
    .
    return (int) msg.wParam;
}

This has been fixed for some time.  The MSG struct is now zero-initialized:

MSG msg = {0};

I'll confirm in the debugger and close the issue.

I just confirmed that the MSG structure is cleanly initialized, and that the program terminates with the expected success return code during normal operation.

Closing as resolved.
