Yeah, I can imagine this being very annoying to track down. This is very
unfortunate. I remember looking at this problem a some time ago because it was
causing failures on one of the bots, and not being able to conclude where this
ignore is coming from. It looks like svn just doesn't like .so files
altogether. Well.. I guess that's one more thing that will be solved be the
impending switch to github.
Does this mean the direcotory-clearing part can be removed now? I've tried the
test on a mac and it still succeeds for me. If it doesn't work for you, it
looks like we still have some kind of nondeterminism in here, and I'd like to
get to the bottom of that. FTR: this is the stack trace of the point where lldb
find the module for me:

As you can see, the code happily constructs the right path based on the
exec-search-path setting even though we are setting the full path on the input
file spec. Can you please check why your lldb fails to reach this place?
