warning: GDB can't find the start of the function at 0x77f1af5a.

GDB is unable to find the start of the function at 0x77f1af5a

and thus can't determine the size of that function's stack frame.
This means that GDB may be unable to access that stack frame, or
the frames below it.
This problem is most likely caused by an invalid program counter or
stack pointer.
However, if you think GDB should simply search farther back
from 0x77f1af5a for code which looks like the beginning of a
function, you can increase the range of the search using the `set
heuristic-fence-post' command.
(gdb)

我们先看一下，稍后回复

目前根据gdb的信息以及代码分析，没有看到异常的问题。
能否在你们平台上验证下以下代码是否可以正常运行：

#include "cJSON.h"

int test_json()
{
	char *buf = "{\"uuid\":\"3xCy08F3HUOxHN24UKRg\",\"auth_key\":\"nXDxHOktvAViGApuCtIeIgBREa9T8iYB\",\"ap_ssid\":null,\"ap_passwd\":null,\"country_code\":null,\"prod_test\":false}";
	
cJSON *root = cJSON_Parse(buf);
if(NULL == root)
{
    printf("json parse fails\n");
    return -1;
}	

cJSON *json = cJSON_GetObjectItem(root, "uuid");

if(json){
	printf("get uuid ok\n");
} else {
	printf("get uuid fail\n");
}
return 0;
}
