I've tried to remove this particular assert statement at "JSCast.h:143": // ASSERT_UNUSED(vm, canCast == from->JSCell::inherits(vm, Target::info()));
... and now application crashes at different assert statement: > jfxwebkit.dll!WTFCrashWithInfo(int __formal, const char * __formal, const char * __formal, int __formal) Line 672 C++ Symbols loaded. jfxwebkit.dll!JSC::InternalFunction::finishCreation(JSC::VM & vm, const WTF::String & name, JSC::InternalFunction::NameAdditionMode nameAdditionMode) Line 49 C++ Symbols loaded. jfxwebkit.dll!JSC::RuntimeMethod::finishCreation(JSC::VM & vm, const WTF::String & ident) Line 58 C++ Symbols loaded. jfxwebkit.dll!JavaRuntimeMethod::finishCreation(JSC::VM & globalData, const WTF::String & name) Line 231 C++ Symbols loaded. jfxwebkit.dll!JavaRuntimeMethod::create(JSC::JSGlobalObject * globalObject, const WTF::String & name, JSC::Bindings::Method * method) Line 212 C++ Symbols loaded. jfxwebkit.dll!JSC::Bindings::JavaInstance::getMethod(JSC::JSGlobalObject * globalObject, JSC::PropertyName propertyName) Line 241 C++ Symbols loaded. jfxwebkit.dll!JSC::Bindings::RuntimeObject::methodGetter(JSC::JSGlobalObject * lexicalGlobalObject, __int64 thisValue, JSC::PropertyName propertyName) Line 124 C++ Symbols loaded. jfxwebkit.dll!JSC::PropertySlot::customGetter(JSC::JSGlobalObject * globalObject, JSC::PropertyName propertyName) Line 48 C++ Symbols loaded. jfxwebkit.dll!JSC::PropertySlot::getValue(JSC::JSGlobalObject * globalObject, JSC::PropertyName propertyName) Line 422 C++ Symbols loaded. jfxwebkit.dll!JSC::JSValue::get(JSC::JSGlobalObject * globalObject, JSC::PropertyName propertyName, JSC::PropertySlot & slot) Line 963 C++ Symbols loaded. jfxwebkit.dll!JSC::LLInt::performLLIntGetByID(const JSC::Instruction * pc, JSC::CodeBlock * codeBlock, JSC::JSGlobalObject * globalObject, JSC::JSValue baseValue, const JSC::Identifier & ident, JSC::GetByIdModeMetadata & metadata) Line 759 C++ Symbols loaded. jfxwebkit.dll!llint_slow_path_get_by_id(JSC::CallFrame * callFrame, const JSC::Instruction * pc) Line 833 C++ Symbols loaded. jfxwebkit.dll!llint_entry () Unknown Non-user code.
