Well, it doesn't work on my machine without the patch I sent in. That is,
strace *always* traces child processes for me regardless of the -f flag.
This is true of both the last release (1.3.10) and the current cvs source.
I've also got a test program that shows exactly the same behaviour unless
the CreateProcess() debug flags are used as per the patch I appended to the
last email message. And I've checked that that patch does change the
behaviour of strace with child processes (for me, on my machine, etc.).
If it's working for you, I'm not quite sure where that leaves us: I'm
running w2k (w/ latest service packs etc.), on a Pentium something-or-other
box, nothing too wacky.
Have you any idea? I'm befuddled now.
