- I hope you don't mind me answering your question with approximately the
- same level of detail that you have provided:
-
- The body of your new system call has a bug.
-
- Why don't you try "nullifying" half of the body of the call to discover
- which half has the bug? After that, nullify half of what's left to
- narrow it down further. Repeat until you know what the bug is.
- Simple, no?
