System name: yaz-pistachio
Type and version: MVAX-II 7.1H
Display type: QVSS
What were you trying to do?
Run xrn (from the sipb locker).
What's wrong:
It has a bug that causes it to exit with return status 11111111b.
Yesterday, I was on an RT when it happened, and the shell reported
that xrn exited with status 255; today, on a vax, the shell reported
an exit status of -1.
I assume that one of them is *wrong*. This could potentially break
some programs/shell scripts that depend on return values being
correct.
What should have happened:
I should have seen the same exit code on both machines, whichever way
it is actually supposed to be.
