Only just had a chance to look at this but yes, I think this is a
problem.  I'm not really sure why this assignment is needed, but if it
is it should reassign to a previously opened file.  Possibly the right
thing to do is to keep a separate FILE *xtrace_file which always points
to the file opened in xracefdsetfn or stderr if none (so no file
management is ever done directly on this, it's simply a pointer to the
FILE opened to the last trace file requested by the user or stderr if
none).
