            Bug ID: 20884
           Summary: stack content suddenly changed
           Product: gdb
           Version: 7.11.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: nabil.rahiman at gmail dot com
  Target Milestone: ---

0x0804ad31 <+0>:        push   %ebp
   0x0804ad32 <+1>:     mov    %esp,%ebp
   0x0804ad34 <+3>:     push   %ebx
=> 0x0804ad35 <+4>:     sub    $0x24,%esp
   0x0804ad38 <+7>:     mov    0x8(%ebp),%eax

(gdb) x $ebp + 8 
0xbfffed40:     0xb6a0d018

(gdb) si

   0x0804ad31 <+0>:     push   %ebp
   0x0804ad32 <+1>:     mov    %esp,%ebp
   0x0804ad34 <+3>:     push   %ebx
   0x0804ad35 <+4>:     sub    $0x24,%esp
=> 0x0804ad38 <+7>:     mov    0x8(%ebp),%eax
   0x0804ad3b <+10>:    sub    $0x8,%eax
   0x0804ad3e <+13>:    mov    (%eax),%eax

(gdb) x $ebp + 8 
0xbfffed40:     0xb6b67048

I’m not sure why when the value of $ebp + 8 changes ..
