Something went wrong during a factorization (while trying to rename a file
in the MPQS factorizer).
This is a recurrent problem on Windows, that we tried to fix a few
times; pari-2.5.5 is old now (codebase from 2011 or so), try to update
to 2.7.3 !

No, the computation was stopped before completion.
You should have typed 'x' while still in the debugger (break loop),
*before typing 'break' to see up to which value the sum had run.
N.B. sum(x=1,n, moebius(x)) is a simpler form for the same computation.
