Re: [xml] Questions about libxml as a DLL on win32.

[Steven M Cherry <smc cherrys org>]

Did you compile and run my sample program ?  It demonstrates my point
pretty well.

Note, also that this problem can often be a silent one.  Your app might
not crash due to memory problems, but does it leak?  Have you watched
your memory traces to verify that everything is released properly, and that
your memory useage actually goes down?
