Google Chrome - Crash Dump Location

Question

I'm trying to debug a page in a web app that keeps crashing Chrome ("Aw, snap!" error). I've enabled/disabled automatic crash reporting, tried logging with google-chrome --enable-logging --v=1, (as well as various levels of verbosity), and all I get is a "crash dump ID" in the chrome_debug.log chrome://crashes Shows all of the dump IDs, but no actual dump file

I see other questions referring to reading the dump files, but I can't find the dump files themselves (just the ID).

Grepping for the crash ID in /tmp and ~/.config/google-chrome/ turns up nothing, but the ~/.config/google-chrome/chrome_debug.log shows that something was sent:

--2015-04-06 11:10:00--  https://clients2.google.com/cr/report
Resolving clients2.google.com (clients2.google.com)... 74.125.228.224, 74.125.228.225, 74.125.228.231, ...

 Crash dump id:  7dac9d5d58258264 

Any ideas on where to find the actual file/data that's sent?

Details: Chrome version: 40.0.2214.111 (Official Build) Linux Mint 16 (Petra)

Edit: Some extra info:

Thanks!

Google Chrome - Crash Dump Location

To generate the Crash Dump locally,

 CHROME_HEADLESS=1 google-chrome

The .dmp files are then stored in ~/.config/google-chrome/Crash Reports

Produce Stack Trace

1. Check out and add depot_tools to your PATH (used to build breakpad)

   git clone https://chromium.googlesource.com/chromium/tools/depot_tools
   export PATH=`pwd`/depot_tools:"$PATH"
   

2. Check out and build breakpad (using fetch from depot_tools)

   mkdir breakpad && cd breakpad
   fetch breakpad
   cd src
   ./config && make
   

3. To produce stack trace without symbols:

   breakpad/src/processor/minidump_stackwalk -m /path/to/minidump
   

More here https://www.chromium.org/developers/decoding-crash-dumps

Personally Preferred Method

1. Enable crash reporting:

   Chrome menu > Settings > Show advanced settings > Tick "Automatically send usage statistics and crash reports to Google"

2. Go to chrome://crashes > File bug > Takes you to crbug.com > Complete report leaving the auto-added report_id field unchanged.

3. Someone from the Chrome/Chromium team will follow up. They can provide you with your stack trace and aid at resolving the issue.
