Hi all,
I tried compiling the above two programs :
on x86, 32 bit machines.
And when I used objdump on that I saw the following code.
Can anyone help me know,
Why in the objdump of our first program the esp is decremented by 18H bytes
and in the second program the esp is decremented by 28H bytes.
Hello everyone,
While scrolling down the objdump of the code for /usr/bin/gcc, There
is a section called text.hot section, which is normally not present on
the elf files. What is that? is it something specific to /usr/bin/gcc
only.How can be create such sections in our normal executables ?

the details in an atricle named GCC-INTERNALS, It said that we have a
macro with the following name TRAMPOLINE_ADJUST_ADDRESS (addr).
The explaination to it said that this is used mainly to perform any

Hi Everyone,
int
main ()
{
int *p;
int i;
p = (int *) malloc (400 * sizeof (int));
for (i = 0; i < 512; i++)
{
p[i] = i;
printf ("p[%d]: %d\n", i, p[i]);
}
return 0;
}
The following code should terminate with Segmentation fault, right ?
But when
