a core when error string with ”

[chinchilla-forest]

Hi i find a core when use error string to a parser。
My code is：
char my_string[1024] = "{\"name\": \"Jack \" Nimble\"}";
printf("string is %s\n",my_string);
cJSON *root = cJSON_Parse(my_string);
if(root ==NULL)
printf("parse error");

and the result is ：
string is {"name": "Jack " Nimble"}
Segmentation fault

it is core in cJSON *root = cJSON_Parse(my_string);

and if i change the string to right json：
char my_string[1024] = "{\"name\: \"Jack Nimble\"}";
it is work well。

sorry I am wrong。For my question, the compiler should optimize my code. My subsequent code will still call root, and he may be executed before the error is printed.
