This looks like an atexit() handler `error()' trying to print a

The CVS code is doing some iffy things in general: like calling
exit() from within atexit() and signal handlers.
This is actually fallout from the work that christos@ and I are
doing to make stdio's writes restartable in the face of transient
I/O errors--like EINTR. Our ATF test missed this scenario. Christos
has already committed the fix. Sorry for the inconvenience.
