How to solove warning recursive call to a constant

Jun Wei

I have following codes:

void fun1(unsigned char *msg);

void fun2()
{
fun1("ssss");
}
void fun3()
{
}
code void (*func_array[])()={fun2, fun3};

void fun1( unsigned char *msg)
{
(*func_array[1])();
}

void main()
{
(*fun_array[0])();
}

when compiling, i got the following message
*** WARNING L13: RECURSIVE CALL TO SEGMENT
SEGMENT: ?CO?HELLO

Could you please tell me how to solve it? Thanks a lot!

    I think my situation is a little different from what those APP discuss.

    PROGRAM RECURSIONS REMOVED FROM CALL TREE
=========================================
+--> ?CO?HELLO
|  | ?PR?FUN2?HELLO
<--+ ?PR?_FUN1?HELLO

    I also check the caller tree, i feel that fun1 overlay has some problem. a strage symbol comes out _fun1, but i don't know how to fix it? pls help. Thanks
