Well, except when people are misled when investigating problems because 
they assume the output is accurate. (e.g. [1])

I guess what's maybe needed is some indication that an error occurred 
and the output may be incomplete if the inferior process exited with a 
non-zero status.  But not sure how we can do that while keeping the 
output compatible with linux ldd.
