Greetings, and thank you so much for your helpful reply! Was this on an i386? I'm specifically looking for a way to do his on arm, alpha, and sparc, and I don't believe they have the cr2 member of struct sigcontext. Any info you might have, including where you found this solution, would be appreciated!
Take care,
