+      report_fatal_error("at least one definition string must exist");
+    if (VD->vd_cnt > 2)

Hi, I am curious about why the Parents/Predecessor more than one. According to https://akkadia.org/drepper/symbol-versioning 

>  `vda_next` byte offset to the next Elfxx_Verdaux entry.  The first entry (pointed to by the Elfxx_Verdef entry, contains the actual defined name.  The second and all later entries name predecessor versions.

Feel free to ignore me :) just out of curiosity
