Alan, I see your  point and I also believe that they broke it (no matter
what they say) but  the concern here is that php folks may not fix it
and I moved to  5.3.7 for a reason (promise of better fpm support)

isn't; changing is_a to instance of a better solution? Maybe I can do
that for HTML_Template_Flexy (because I use it) and send you the
patches??

Let's follow the bug and see what happens, I think it's a serious BC
break. It's changing the 
documented behaviour...

Maybe not, but some people say that is_a() in 5.3.7 is working as it
should, but that changing behavior in a minor release is no good. And
that 5.3.8 might fix this, but that in 5.4 is_a() will be changed to
work as it currently does in 5.3.7

Perhaps, just to be a little ahead of time, it should be fixed anyway?

It's a known bug in 5.3.7, 5.3.8 is comming out very soon, so I'm not
sure it's worth fixing.

Description:
------------
In php 5.3.7 is_a() will now trigger the autoloader if the first
argument is not an object.

DB_DataObject uses a line like:
if (is_a($this->$k,'DB_DataObject_Cast')) {
in several places, but in most cases $this->$k is a string, and it will
then trigger any __autoload() you have in your project. 

Which again will result in warnings thrown by php when the file is not
found. 

These warnings are annoying, but DB_DataObject is still working as it
should.
