Windows Server 2012.

Note: I did notice that there was an issue regarding V8 Proxy resolver and the kSingleProcess flag that was recently resolved (

Possible dupe, but haven't been able to verify that eroman's fix resolves the issue I'm seeing.

Found these log files from when Chrome failed to launch. Couldn't interpret anything from them, but maybe someone else more familiar with the project can :)

Also, I tried several previous version of Chromium from the snapshots back through January and all of them exempted the same issue on my Win Server 2012 machine and my Win 8.1 machine.

Most notably, I tried several builds older than 318277 which is what regressed the issue tracked in the bug I linked to earlier. So that leads me to believe with high confidence this is a different issue.
Those files are WER (Windows Error Reporting) report files. Did a "Google Chrome is not responding" or "Google Chrome has stopped working" dialog appear? Windows Error Reporting (WER) is WerFault.exe in Windows/System32

Your current Chromium version is lower than the current Chrome Canary version (canary is slightly older than Chromium). Can you reproduce this issue on the latest Chromium build or the canary build? (You can download Chromium from or Chrome Canary from

Thank you for filing a bug!

Yes, this repros with all of the recent versions I've tested with (approx 15 or so ranging from build 272511 all the way to today's most recent snapshot).

Again, the steps I'm doing to repro are: 
Download and extract any snapshot zip.
Create a shortcut for the chrome.exe.
Modify the shortcut Target to include the --single-process flag. 

Alternate repro is to open command line and navigate to directory of chrome.exe and execute "chrome.exe --single-process"

The following revision refers to this bug:

commit f71a0add64e543c7bb4cf59442b77ec5f3f6978e
Author: yoichio <>
Date: Fri May 08 04:03:38 2015

ExtensionFunctionDispatcher should use base::Process::Current() if single process

Since #323179, ExtensionFunctionDispatcher has used
base::Process::DeprecatedGetProcessFromHandle to callback:
However, base::Process::DeprecatedGetProcessFromHandle(handle) assumes
 |handle| is not current process handle. The assumption brakes if single process mode
 thus chrome can't start with the '--single-process' flag.

There are still many components to be fixed.

I've just tried this on v46.x and still receive the crash on Win 7 and Win 8.1.  Is there a fix coming?  I need to upgrade from my current working version.

I'm not sure and I don't have enough bandwidth.
It works on Windows 8.1.
Anyone can confirm on your environment?

Feel free of un-merge, if someone feels otherwise.

Thank you!

It's 2018, and Chrome still crashes due to this setting
Is single process mode not supported officially? This is really a useful mode in testing area. It is not working for 3 years, really sad.
