How to get more info when the "Aw Snap" screen shows up in Chrome?
First enable Automatically send some system information and page content to Google to help detect dangerous apps and sites from Settings -->> Advanced -->> Privacy and Security
then enable Crash reporting in Chrome as below
- Open chrome://crashes
- If it shows crash report as disabled, enable it. If crash happens it will dump the crash report at C:\Users\{username}\AppData\Local\Google\CrashReports
This would give more info when the aw snap screen shows up in chrome
I don't know if you'll see much in the non-debug build but try turning on logging and see what shows up:
Launch Chrome with these flags: --enable-logging --log-level=0
On Vista your log file would be in:
C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default
On XP your log file would be in:
C:\Documents and Settings\<username>\Local Settings\Application Data\Google\Chrome\User Data\Default
See http://www.chromium.org/for-testers/enable-logging for details.
When you run DevTools on the website which is about to crash, it may give you some clues.
For example, when the tab will hit out-of-memory limits, the debugger will pause the code just before the crash (Chrome, Opera, etc.). The memory usage can be checked in the Memory tab.
If the cause is different, run Chrome from the command-line with --enable-logging --v=1 and check the logs (system logs and chrome_debug.log file).

macOS
If you're on macOS, such crashes should be automatically reported. They can be checked in Console app and check for Crash Reports. Or find them in Finder, the files are located in /Library/Logs/DiagnosticReports (system-wide) and ~/Library/Logs/DiagnosticReports (user).
Check also Chrome logs in real-time, by:
log stream --level debug --predicate 'processImagePath contains "Google"'
