Hi cinap,

I could not find it either.  I recreated the problem and it seems APE's
stat generates that error somehow.  See the attached test program
(compile with pcc).  Maybe the message is somewhere in APE, although I
could not find it in /sys/src/ape either.  If it is in APE, the errno or
the errmsg could be fixed there, of course.

Thanks, benny
