Follow-up Comment #1:

The attached patches should resolve the material problems with atexit and
fprintf.

There are remaining calls to fprintf which are not checked, but these are for
debug information or error message generation.   In the latter case there is
no point diagnosing a failure to write to stderr by writing to stderr, and the
return value is already nonzero.

The patches are attached.
