I've been trying to recreate this with a vanilla llvm-project checkout and build on windows, but I'm struggling to get it to work. The problem itself shows up in our automated testing which is part of a larger application, so creating something standalone is difficult.

However, if you check out llvm with a long path (say c:\Testing\MyLongPath\MyReallyReallyLongPath\ThisIsVeryLongIndeed\llvm-project) you should see the problem.
Alternatively, if you simply mount a directory as a new driver using subst (subst x: c:\Testing\MyLongPath\MyReallyReallyLongPath\ThisIsVeryLongIndeed) and build/run llvm-lit testing from x:\llvm-project, you'll see that the llvm-lit will use the original c:\..... path rather than the new x: drive
