I have a problem with "Set memory range breakpoint" in each variation (via MR in CommandLine, BPMR in OllyScript etc.). It doesn't intercepts "Access violation" on "rep movsb" like instructions. MOV reg, [addr] works fine. I've tried to make my own plugin with VirtualProtect function using. As I've supposed, ODBG_Pausedex receives data only on MOV reg, [addr] case and never on rep movsb.

Here is my question: why this happens? (maybe optimization inside Olly?) And how could I intercept accept violations without ODBG_Pausedex?

i did not understand your question



but i think you are talking about memory access violations in kernel.dll etc ??

if that is the case
you can uncheck the default checkmark on

options-->debugging options --> exceptions --> ignore memory access violation in kernel32
