Hi Maple customers all over the world,
Be you a student, or a Boeing engineer, or a Canadian math
instructor, let us rejoice at Maple quality improvements
advertised the other day by Herr Richard, Maple Support,
Scientific Computers GmbH.
http://groups-beta.google.com/group/comp.soft-sys.math.maple/msg/83505ab90dd16760
This bug is absent in all versions before Maple 9.5.2/9.5.
Again, as it is almost become a tradition in recent Maple
versions, we observe a side effect.
Rejoice!

Recently, good Maplesoft already vouchsafed us the customers
its advent.
Namely, Mr Paul DeMarco produced the famous Maple 9.5.2 upgrade
http://www.maplesoft.com/support/maple95/General/2.aspx
> "Maple 9.5.2 is an all platform maintenance update to Maple
> 9.5/9.5.1. Maple 9.5.2 provides improvements to the automatic
> simplification of expressions of the form x-x when x is an
> unassigned name."
for the *single* purpose to fix the discovered by our GEMM
machine bug, see:
maple 9.5:
> z-z+z^2+z^3;
> z-z+z^2+z^3;
2 3
z + z
2 3
2 z + 2 z

Subject: not nice
http://groups-beta.google.com/group/comp.soft-sys.math.maple/msg/137d00cd3cc7b8b1
as well as the comments from Axel Vogt!
http://groups-beta.google.com/group/comp.soft-sys.math.maple/msg/5f7855ee33e3b5fc
What about Maple 9.5.3 free upgrade fixing dozens those recent
publicly reported bugs by Cyber Tester to this forum?
(Let us forget for a while about a huge stock of Maple bugs
reported at the Maple Bugs Encyclopaedia, speaking far less
about the upgrade coming.)
So long... Remember, behave yourself!
Be as good as pie, obey your superiors,
be fond of your own kind...
And Maplesoft could vouchsafe you..... maybe.
