            Bug ID: 48998
           Summary: ClangdTests/GlobalCompilationDatabaseTest.BuildDir
                    sometimes goes in an infinite loop
           Product: clang-tools-extra
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: clangd

I think I saw it once on Linux, but recently I only see it on the arm mac bot
(arm has a less serialized memory model), here:

http://45.33.8.238/macm1/2804/step_8.txt
http://45.33.8.238/macm1/2654/step_8.txt <- oh here it was
GlobalCompilationDatabaseTest.FallbackCommand

Scrolling through the logs, that's all I see right now.

The mac arm bot has been around since December last year but the flakes have
only appeared in the last few days. So maybe it's some kind of regression.
