Thanks for the response! –TheArcher Jun 22 '10 at 2:47 add a comment| up vote 0 down vote I don't know why but bochs with gdb-stub enabled seems to be picky And sstepbits would be "ENABLE=1,IRQ=2,TIMERS=4". This makes it much harder for the attacker to guess what will be the value he wants to store (through a buffer overflow) over the "return address" slot.

With the IRQs and and timer service routines on, a single step might jump into the one of the interrupt or exception vectors instead of executing the current instruction. Any ideas what is happening? There are several protection mechanisms related to buffer overflows in a Linux system (I assume you are using Linux): The stack can be marked as "non executable". http://amigasuperbit.com/cannot-find/qnx-cannot-find-bounds-of-current-function.html When trying the sstep I felt it was easy to get confused with the negated bitmasks.

How to reply? Well, the credits certainly goes to Jason.... well, IMO, you don't need -O at all. Type "show copying" to see the conditions.
