mach_override: some instructions unknown! Need to update mach_override.c #25

Hello there,

I try to override any method, it always fails with trail of messages.

mach_override: some instructions unknown! Need to update mach_override.c err = f8000001 /Users/test/Desktop/NewInjectionTest/Injecant/mach_override.c:227 err = f8000001 /Users/test/Desktop/NewInjectionTest/Injecant/mach_override.c:240 err = f8000001 /Users/test/Desktop/NewInjectionTest/Injecant/mach_override.c:246 err = f8000001 /Users/test/Desktop/NewInjectionTest/Injecant/mach_override.c:260 err = f8000001 /Users/test/Desktop/NewInjectionTest/Injecant/mach_override.c:265 _CGContextSetLineWidth Override failed! mach_override: some instructions unknown!

I am mach_inject.h /.c file for injection and mach_override.h/.c for overriding. I use sudo with executable in oder to inject. Injection appears to be successful with message,

mach_inject failing.. (os/kern) successful mach inject done? 0

But overriding fails.

I am using 10.6.8 OS X version and XCode 3.2.

Am I doing something wrong?

Why was this issue closed?

There were a fix around 3-4 months ago (Nov 02, 2011 and Nov 09, 2011). That has fixed this problem. However it can still be reproduced, but only for some cases.

I will test more and will log different issue for it.
