Hi Marco,

Thanks a lot for your code. After a bit of tunning (GCC 3.2.2 adds a 8
bytes pad between vars and BP) it's working. Now it just rests to figure
out why mine one didn't work ;)

Best regards,
Emilio Mira

Hey Emilio,

Find a working example attached, based on the second technique described
by Nergal in his "Defeating Solar Designer's Non-executable Stack Patch"
paper. Hope you'll find it useful :)

Cheers,
