As I said, just to bother developers. This is purely an anti-debugger call.

Search PT_DENY_ATTACH in google for some way to workaround this and fill a radar to explain that this is a problem.

Yes, it happens every time, even when no project is open.

Also, if I open FCP 7, first, then try to attach to the process, the debugger
fails with an exit status 11. (and FCP stays running.)


Is there a way t find out what it invoking the PT_DENY_ATTACH ?

Anyone know what "exit status 45" means?


Yes, that ptrace has been call with PT_DENY_ATTACH prior debugging.
It may be due to Apple adding this call in FinalCut Pro 7 (which would be useless except to annoy developers) or because some library call this under the hood. It may append with QuickTime when you read some protected file. Does it append everytime (without any project opened) ?
