Have you ever used Windows Debugger? This is a debugger extension for Windows Debugger.

I also wrote the following article about PartitionAlloc before. It might be helpful if Google translate works well.

thanks!I know a little about windbg, but how to install it into windbg?
Do I need to compile this project myself?

Can it be used directly to debug release chrome?thanks!

Yes, you need to build this project first. Build steps are easy. Download the latest Visual Studio Community (or other editions if you can afford to pay for it), open "x86/x64 Native Tools Command Prompt", and run NMAKE without any options. Then you'll get a extension DLL cr.dll, which can be loaded by running the debugger command .load <path to cr.dll>.

You don't need to build Chromium on your own. This works with the official Chrome/ChromeCanary. To do that, you need to get the private symbol. Please check the section "Symbol server" in the following page. Actually if you use your private Chromium, you need to modify the extension's code because the name of Chromium's core module is different and I hardcoded the name as chrome_child.dll.

The page above introduces some parameters for chrome.exe that might be helpful, but it's just optional. Just launching Chrome as usual, and attaching your debugger to a render process is good enough.

I have not used this extension for a while. Probably it doesn't work with the latest Chrome now. I'll check and update if needed.

I've updated PartitionAlloc commands so that you can use it to debug Chrome 70.
