Issue #2303 has been updated by Vlad Why.


As i know, DEP prevents execution of the code on the stack. It does allow to load dll's.  On winXP DEP is enabled only for the system services. You may enable it for all programs : my computer->properties->advanced->Performance Settings-> DEP -> turn on DEP for all programs.  It makes a little bit harder to exploit a buffer overrun.
