I am running ubuntu on VMWARE and when i try to access the memory at $esp,I get the error as shown in the screenshot below.I've tried googling for answers but most of them were too complicated.
Is there any configuration I need to do for this to work?
I've tried running gdb on my actual windows machine and it does not have this issue.
$esp, you got the sign-extended 32-bit-truncated value of
$rsp, which points to neverland.
Note: GDB provides
$sp pseudo-register that is automatically mapped to correct stack pointer register for a given platform.
(gdb) p $rsp $1 = (void *) 0x7fffffffe178 (gdb) p $sp $2 = (void *) 0x7fffffffe178 (gdb) p $esp $3 = -7816 (gdb) p/x $esp $4 = 0xffffe178
