a diff of symbols exported by current libafflib0 and a rebuilt one
shows among others:
-_ZN3aff7seglist8containsESs
+_ZN3aff7seglist8containsENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
-_ZN3aff9ends_withERKSsS1_
+_ZN3aff9ends_withERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEES7_
Both of these symbols are public.
Cheers,
Julien
