I'm trying to use the memory/leak tools provided, I need some
clarification on a few things if possible.
A basic navigate to google.com and then shutdown of my app yeilds about
the same "leakage" as the MFCEmbed app does. Here is where I'm a little
confused...if I click on the link to froogle and then shut down, I get a
WHOLE lot of reported leaks. But if I go to news or images...any of the
other links there on google.com, the reported "leakage" is the same as
just loading google.com and shutting down.
I've attached both reports to this email...I don't have a lot of
experience with this so I'm not sure if this is "expected" or not.
Something else I noticed. I WAS getting that nsWindow, nsWebBrowser
and one other...dang can't remember..were leaking...I changed my
nsIWebBrowser object from an nsCOMPtr to a standard raw pointer and
released them myself on shutdown and it got rid of those leaks. I'm
wondering...since it was an nsCOMPtr, could it be that the leak stats
finished up before the nsCOMPtr had a chance to call the destructor on
that object? Thanks to anyone who can provide any info on this!
