I want to make a php extension on windows and also on linux, but i've got a function that give me core dump on linux, but on windows works.

PHP_FUNCTION(test_string)
{    
   char *arg = NULL;
   int arg_len, len;
   char string[256];

   if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &arg, &arg_len) == FAILURE) {
       return;
   }

   len = sprintf(string, "String:%s", arg);
   RETURN_STRINGL(arg, arg_len); 
}

What PHP version are you targeting? If PHP 7, then `arg_len` must be ? size_t`. – NikiC Sep 01 '16 at 10:30
