[lldb-dev] top-of-tree build failure when using configure on Linux?

[Todd Fiala via lldb-dev]

I haven't seen that one myself.  Are you still seeing it?

Is it possible the buildbot's commands are possibly using older/stale
object files?  Is distcc/ccache involved?  Does the build force a clean
build?  If not, does the issue go away on a clean build?  Is it
configure-based or cmake based?

Just some thoughts.  Good luck resolving!
