cannot ktrace compat netbsd32/linux32 binaries

[Nicolas Joly <njoly%pasteur.fr@localhost>]

Hi,

I just got a new machine at home (Dell Optiplex 740) running
up-to-date -current, where i cannot run ktrace on compat netbsd32 or
linux32 binaries ... it seems to abort early, even before running the
expected command.

Any idea ?

Thanks.
