关于UE4 EXCEPTION_ACCESS_VIOLATION 崩溃该如何解决？

Question

现在就是每打开此关卡，进不去就直接崩了，唯一解决就是迁出来，重新创工程。但是还是坚持不了半天就又会崩溃，紧接着就没了。

Answer 1

Action ( )
{
char * x_p;

    lr_save_string ( "hello_world!",  "MESSAGE" );
    x_p =  ( char * )strchr (lr_eval_string ( "{MESSAGE}" ),  ‘ ‘ );
   
     if (x_p )  // if the pointer is not NULL display correct message
     {
            lr_save_string (x_p,  "MESSAGE_FROM_SP" );
            lr_output_message (lr_eval_string ( "{MESSAGE_FROM_SP}" ) );
     }
     else  //if pointer is NULL display error message
     {
            lr_error_message ( "Space not found in MESSAGE parameter" );
     }
     return  0;
