Single Test Failure possibly due Locale.

[AdamSpeight2008]

This the second time I've encountered this single test failure.

      <test name="Microsoft.CodeAnalysis.UnitTests.Diagnostics.DiagnosticLocalizationTests.TestDiagnosticLocalization" type="Microsoft.CodeAnalysis.UnitTests.Diagnostics.DiagnosticLocalizationTests" method="TestDiagnosticLocalization" time="0.031" result="Fail">
        <failure exception-type="System.Collections.Generic.KeyNotFoundException">
          <message><![CDATA[System.Collections.Generic.KeyNotFoundException : The given key was not present in the dictionary.]]></message>

        </failure>
      </test>

if I build via jerkins no failures.

I think it was introduced somewhere between #958 (no failures) and #1001 (1 failure)

I thought this could be due to 356854d ( #985 ), but that was merged into dotnet/roslyn late yesterday night and your issue was filed before that. So something else seems to have caused this. I am unable to repro this failure locally either. Does this repro consistently on your machine? If so, could you collect a dump and share it?

[AdamSpeight2008]

My repo master has first initiated at the at 97b84b5
and no build or test issue occurred For r#1001 to sync I had to Pull and the from on the test has had the one failure since. Hence to reference to the two pull request as I know that somewhere between them it was introduced. I'm not saying it was you, it could easily be something to do with my repo / setup.

My machine is in the Locale (UTC) Dublin, Edinburgh, Lisbon, London but the VS2015ctp6 is English (USA)
I'll clear out the bin folder and rebuild and test.

Thanks, that information helps, let me try to setup a machine with your environment and try to get a repro.

[AdamSpeight2008]

I'm just doing the clean build and test which usually takes about 30mins. I'll add and update once it's complete.
Build: OK
Test: Bad (That 1 failure again)

Haven't seen this repro so I'm marking it as verified.
