This is a race condition when we use nsinstall.py to copy pdb files in the asan build. nsinstall.py uses os.mkdir in this case:
https://dxr.mozilla.org/mozilla-central/rev/c291143e24019097d087f9307e59b49facaf90cb/config/nsinstall.py#117

...but doesn't handle the "directory already exists" case. Humorously there's already a `maybe_create_dir` function in that file, so we could probably just change that line to use that function instead:
