I have realized that results from rt.bat differ from those when running buildrelease.bat (see example below)
Why do the tests run OK in rt.bat but fail in buildrelase.bat?

To my best understanding, the tests are summoned directly via rt.bat but also from buildrelease.bat (because these are used to generate data for the PGO optimization process right?)- but when run from the buildrelease.bat file, the tests are in "silent" mode, just fatal errors are displayed at the command prompt as opposed to <rt.bat -x64 -wW>.

Is there a way to pass some arguments to buildrelease.bat so that the tests run in verbose mode? This is important, because that way i can know exactly which tests fail.
