I was running "make check-very-expensive -j 10 -l 4", and as misc/tty-eof
is quite at the top, "make" maybe didn't have a chance to balance to load
4 yet. It happens only under heavy load (CPU and disk), but I can not
reproduce it under "normal" conditions. However, with "-j 10 -l 4",
I hit it quite regularly (1 out of 4 times).
And sometimes, the "tac" error message is not there, only the "sort" error
is there.
Any idea what is going on?
Have a nice day,
Berny
