No, this was in the new version of Appender, though the reason for that new version existing was to fix memory corruption bugs in the old version. The reasons why this one went undetected for any length of time were because it was only in SVN releases and it only became apparent when using Appender to store data structures that have pointer indirection. Storing ints or something would just make the GC more conservative because it would think the block had pointers.<br>

</div>Hrm.. isn't this like the 3rd or 4th memory curruption bug in it? Any<br>
thoughts on what can be done to make it less risky, better tested, etc?<br>
<br>
Does this bug exist in the current public release or was it introduced<br>
during this cycle? If it's out in the wild, that raises the urgency of<br>
getting a release out, imho.<br>
<br>
Later,<br>
