Thank you for the suggestion:

Thanks for the update, and the work to narrow your problem down.

emailed about the same warnings in April (the mailing list archive is
currently down so I can't provide a link, but I can find it in my gmail

Would you happen to have a minimal example of “MyOwnCode.cxx” that reproduces
this warning?
Thanks,

Hi all,
I'm trying to rebuild my app and all its C++ libraries with -fvisibility=hidden
-fvisibility-inlines-hidden. It all builds, but I get 3 very similar link
warnings building my app; the first is:
ld: warning: direct access in function 'itk::MetaDataObject
>::GetMetaDataObjectTypeName()
10 matches
