Say ur variable is a then

$gdb myprogram
Set a breakpoint on ur function say myfunc
gdb> b myfunc
gdb> r

Now program will stop at myfunc
Use p to print the variable

gdb> p a  ----- say value is 5 -----
gdb> 5
gdb> p a=8  ----- this will set the value as 8 -------
gdb> p a
gdb> 8

How a function can access value of local variable of another function whose stack is already gone?

Even I have similar problem:

int (*pfun)(void);
int *pInt = 0;
void fun1()
{
    int i = 5; /* Local to fun1*/

    printf("Outer function");
    pInt = &i; /* As I know address of local variable is valid till function execution */

    int fun2()
    {
      printf("innerfunction");
      printf("%d", *pInt);
    }
    /* fun2 address assign to pfun so that It can be called even after completion of fun1 */
    pfun = fun2;
}

int main()
{
    fun1();
    pfun();
    return 0;
}

Can someone please explain ? I am getting *pInt value 5.

GDB: look at the assembly at certain address how to debug?

I am working on some JIT compiler and I am using GDB to debut it, my code crashes at some point (segment fault), but it crashes at the jitted code (they are generated on the fly) so I do not get the stack frame information, But I got the following backtrace:

#0 0x**********d98f22 in ?? () // JITTED CODE
#1 0x000000000000001d in ?? () // JITTED CODE
#2 ...callattribuite function....

I am wondering if it is possible for GDB to disassemble the code at location 0x**********d98f22 and display it to me. I tried disas 0x**********d98f22 but GDB complained No function contains specified address.

Any clue?
