Public bug reported:
On a qemu chroot with Ubuntu 9.04 installed:
find /usr -print0 | xargs -0r pwd
produces:
Error loading /bin/pwd
Error loading /bin/pwd
Error loading /bin/pwd
Error loading /bin/pwd
/bin/pwd: ignoring non-option arguments
/usr/src/packages/BUILD/xargs
(pwd is just a quiet command)
note that many other 'sensible looking' commands such as
find /usr -print0 | LANG=C xargs -0r |wc
don't show the problem.
nor does
find /usr -print0 | xargs --max-chars 128000 -0r pwd
This can be fixed by changing lib/buildcmd.c : 502 to use a lower value as the
"sensible_arg_max"
enum { arg_size = (128u * 1024u) };
Whilst qemu should have a higher arg_max, I think xargs is at fault
since it is hitting an internal hardcoded limit.
