I've got some problems with new strace mechanism too :( Issuing
command

strace -otrace.dump -f man man

leads to some strange results.

At least one thing that had to be added to strace.cc code is to make
it handle EVENT_EXCEPTION. Sometimes stracing "man man" just freezes
because /usr/local/bin/tbl (called by man) traps and starts to send
EXCEPTION event to strace process over and over again.

Would you consider making selection between new and old tracing scheme
to be an option at dll build time?

I've even built strace.exe under mingw, but results was the same. :(

Sometimes strace.exe just got killed by kernel (i've inserted debug
printf at the exit from main cycle at proc_child, but it didn't show
up), and groff, had been left alone and popped a dialog window that
noone can handle his breakpoint. Can it have something to do with
reparenting?

I'll attach one of strace logs.
