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