Error from the log:
===================
src\breakpad\symupload.exe --timeout 0 C:\b\build\slave\win-asan\build\src\out\Release\vklayer_core_validation.dll http://clients2.google.com/cr/symbol
CoCreateInstance CLSID_DiaSource {E6756135-1E65-4D17-8576-610761398C3C} failed (msdia*.dll unregistered?)
Could not get symbol data from C:\b\build\slave\win-asan\build\src\out\Release\vklayer_core_validation.dll
Failed, 30 before retrying upload.

Could someone please take a look into it. 

Note: 58.0.3024.1 builds are available but still observing a shell failure. Kindly confirm if this was stopped intentionally.

CC'ing few people who can address this.

Thanks.!
