RAD Studio 2009 Ctrl+Z Buffer Corruption Bug

Question

Now this has happened to me twice this week alone: when I press Ctrl+Z a number of times in RAD Studio 2009, the editor buffer gets corrupted. The current and nearby lines get filled with nonsense data, and sometimes a breakpoint is created (autobugically). And there is a EAccessViolationin the IDE, which then terminates. All unsaved code is inevitably lost.

(High-Res)

Is there a cure?

What's the QC number for this bug? If there's a cure, it should be documented there. — Rob Kennedy, Sep 11 '10 at 17:02
I already logged a bug in QC #81814. But cannot reproduce it anymore and the status is "Need Feedback". Maybe you can add more details in QC on that? — markus_ja, Sep 12 '10 at 08:50
I've been noticing this since Delphi 5! It still does this?! — Stijn Sanders, Sep 13 '10 at 11:01

The IDEFixPack for Delphi 2009 addresses the undo editor buffer corruption bug (and some other bugs). This bug was fixed in Delphi 2010 Update 2.

If you've got all the updates installed then there's probably no fix, in that version at least. I believe it got fixed in D2010, though.
