Yes.  That is exactly correct.  The "*.LOG" matches the file
"output.LOG" and therefore includes the output file in the list of
input files.  It has done exactly what you told it to do.

Sure.

Eventually the disk for the output file will be consumed and will
return a write error.

Agreed.  Alternatively you can specify the list of input files not
using a wildcard and therefore also avoid listing the output file with
the input files.

But you didn't report any bugs.  There is no bug there.  You even
described the behavior correctly.  Therefore I am very confused by
your statement.  What did you think was a bug?
