Hi,
I got a USB device driver to fix. Problem, this driver
is leaking memory. I used poolmon.exe, it shows the
memory leak, but I could not figure out the piece of
code which is leaking.
Can anyone tell me the how can I locate the leaking
code?
TIA…

You can also use the windbg command “!verifier” to find out about the
size and content of your allocations; this might give you some good
hints.

There used to be a two file source ( a c file, and a h file) for tracking
memory programmetically up on sysinternals web, not sure if they still have
or not. Also you might some footprint of this on the web somewhere…
They were easy to embedded with other source code, and was very helpful in
finding leaks …

Also you can use John Robbins - Bug Slayer column article and vary it to
link with you application. I used it to find a leak some ISDN call stacks
we had in a driver here. The source code is included with the Bug Slayer
article. It works “kind-of-like” parenthesis matching does where
functions come in pairs - one to allocate another to free. It will show
you where there is a unmatched free.
I can send you (if you want) a tool that is pretty intuitive and
monitors your driver for different types of memallocs (pools/lookasides)
and pinpoints allocations to the source code. I’ve been using it for a
while and it works for me just fine.

This can help a lot of people.
