buggy Solaris /bin/sh cause tramp to fail

[It's me FKtPp ;)]

Hi list,

I get a tramp failure recently. Do you know  if there's already any workaround for this bug?

Note the echo command did not print anything to ouput... And I've checked, that this is the sh builtin test command. 

gtvuas14{nmsadm} # test -e / 2>/dev/null; echo tramp_exit_status $?

gtvuas14{nmsadm} # test -e / 2>/dev/null

gtvuas14{nmsadm} # echo tramp_exit_status $?

tramp_exit_status 1

gtvuas14{nmsadm} # which echo

/bin/echo

gtvuas14{nmsadm} # test -e / 2>/dev/null; /bin/echo tramp_exit_status $?

gtvuas14{nmsadm} # echo tramp_exit_status $?

tramp_exit_status 1

gtvuas14{nmsadm} # echo tramp_exit_status $?

tramp_exit_status 0

gtvuas14{nmsadm} # test -e / 2>/dev/null; echo tramp_exit_status $?

gtvuas14{nmsadm} # echo tramp_exit_status $?

tramp_exit_status 1

gtvuas14{nmsadm} # echo tramp_exit_status $?

tramp_exit_status 0

It feels like the echo command was not executed
