What? Didn't we just fix this (for the case where there's conflicting
debug info from two different libraries)?

(lldb) image lookup -t ...

prints expected results, with no empty classes. Let me emphasize that
the strange behavior is seen with _some_ variables: in the debugging
session referenced in the original email, the problem was particularly
bad.

I didn't try the expensive experiment (-fno-limit-debug-info) on
account of lldb finding all the classes in full.

Is there some systematic way to test lldb? [Looks in the unittests/
and test/ directories]
