To reproduce: 1. Launch MiniBrowser with a debug build of WebKit You'll hit an assertion in ArgumentDecoder::decodeBytes: ASSERT(size == bufferSize); size is 0, bufferSize is 16. Here's the backtrace: > WebKit.dll!CoreIPC::ArgumentDecoder::decodeBytes(unsigned char * buffer=0x01d9377c, unsigned int bufferSize=16) Line 103 + 0x34 bytes C++ WebKit.dll!CoreIPC::ArgumentCoder<WebCore::String>::decode(CoreIPC::ArgumentDecoder * decoder=0x01d98978, WebCore::String & s={}) Line 61 + 0x12 bytes C++ WebKit.dll!CoreIPC::ArgumentDecoder::decode<WebCore::String>(WebCore::String & t={}) Line 58 + 0xd bytes C++ WebKit.dll!CoreIPC::Arguments1<WebCore::String &>::decode(CoreIPC::ArgumentDecoder & decoder={...}, CoreIPC::Arguments1<WebCore::String &> & result={...}) Line 71 C++ WebKit.dll!CoreIPC::ArgumentCoder<CoreIPC::Arguments1<WebCore::String &> >::decode(CoreIPC::ArgumentDecoder * decoder=0x01d98978, CoreIPC::Arguments1<WebCore::String &> & t={...}) Line 44 + 0xd bytes C++ WebKit.dll!CoreIPC::ArgumentDecoder::decode<CoreIPC::Arguments1<WebCore::String &> >(CoreIPC::Arguments1<WebCore::String &> & t={...}) Line 58 + 0xd bytes C++ WebKit.dll!CoreIPC::ArgumentDecoder::decode<CoreIPC::Arguments1<WebCore::String &> >(const CoreIPC::Arguments1<WebCore::String &> & t={...}) Line 66 C++ WebKit.dll!WebKit::WebProcess::didReceiveMessage(CoreIPC::Connection * connection=0x01d987d0, CoreIPC::MessageID messageID={...}, CoreIPC::ArgumentDecoder * arguments=0x01d98978) Line 170 + 0x1c bytes C++ WebKit.dll!CoreIPC::Connection::dispatchMessages() Line 254 + 0x2e bytes C++ WebKit.dll!MemberFunctionWorkItem0<CoreIPC::Connection>::execute() Line 71 + 0x10 bytes C++ WebKit.dll!RunLoop::performWork() Line 62 + 0x1a bytes C++ WebKit.dll!RunLoop::wndProc(HWND__ * hWnd=0x00040478, unsigned int message=1025, unsigned int wParam=31033168, long lParam=0) Line 56 C++ WebKit.dll!RunLoop::RunLoopWndProc(HWND__ * hWnd=0x00040478, unsigned int message=1025, unsigned int wParam=31033168, long lParam=0) Line 38 + 0x18 bytes C++ user32.dll!_InternalCallWinProc@20() + 0x28 bytes user32.dll!_UserCallWinProcCheckWow@32() + 0xb7 bytes user32.dll!_DispatchMessageWorker@8() + 0xdc bytes user32.dll!_DispatchMessageW@4() + 0xf bytes WebKit.dll!RunLoop::run() Line 72 + 0xc bytes C++ WebKit.dll!WebKit::WebProcessMain(WebKit::CommandLine * commandLine=0x0012fed0) Line 58 C++ WebKit.dll!WebKitMain(HINSTANCE__ * hInstance=0x00400000, HINSTANCE__ * hPrevInstance=0x00000000, wchar_t * lpstrCmdLine=0x00021004, int nCmdShow=10) Line 96 + 0x9 bytes C++ WebKit2WebProcess.exe!wWinMain(HINSTANCE__ * hInstance=0x00400000, HINSTANCE__ * hPrevInstance=0x00000000, wchar_t * lpstrCmdLine=0x00021004, int nCmdShow=10) Line 44 + 0x18 bytes C++ WebKit2WebProcess.exe!__tmainCRTStartup() Line 589 + 0x1c bytes C kernel32.dll!_BaseProcessStart@4() + 0x23 bytes
