Probably. Closing a valid file descriptor in itself can't provoke any
error that I can imagine, but fclose() also implies fflush() --- so if
you have written data that hasn't yet been forced out of the stdio
buffers then out-of-disk-space is certainly a foreseeable failure.
fclose failure on an open-for-read-only file seems like Assert()
material; it "can't happen".
