Created attachment 297846 [details] Image will show the backtrace of the crashing thread and backtrace before crash. Scenario: While trying to evaluate javascript using "- (void)evaluateJavaScript:(NSString *)javaScriptString completionHandler:(void (^ _Nullable)(_Nullable id, NSError * _Nullable error))completionHandler;" method. In result when i am trying to print the return value, the application crashes with below message. malloc: *** error for object 0x1704ae520: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I am attaching the info image.
Can you provide a complete reproducible case? This is not enough information for an investigation.
