Bug 233614 – run-webkit-tests: Windows symbols can sometimes not be found "No crash log found for DumpRenderTree"

• Status: NEW
• Component: Tools / Tests

[Jean-Yves Avenard [:jya]]

From time to time, when a process crashed during test, clicking on "Crash Log" takes you to a blank screen with:
"No crash log found for DumpRenderTree:1636."

https://ews-build.s3-us-west-2.amazonaws.com/Windows-EWS/r445267-114626/results.html

There's been times when coming back to that same page several days later will show the crash log as expected.

In post-commit AppleWin Build bot, it doesn't have ntsd.exe
> 19:15:10.897 7468 Can't find ntsd.exe. Crash logs will not be saved.
https://build.webkit.org/#/builders/50/builds/3266/steps/12/logs/stdio

In AppleWin EWS bot, even though it has ntsd.exe, it fails to get crash logs.
> 10:58:41.686 7253 Using ntsd located in 'C:\Program Files (x86)/Windows Kits/10/Debuggers/x64/ntsd.exe'

FWIW, run-webkit-tests successfully collects crash logs for AppleWin port with Cygwin Python on my Windows PC.
