        in pointed to type 'struct krb5_rc_st' at rc-int.h:41:1:

[ben@alien test]$ abidw /lib64/libkrb5.so.3.3 >bar; abidiff  bar
/lib64/libkrb5.so.3.3
Functions changes summary: 0 Removed, 0 Changed (7 filtered out), 0 Added
functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable

$ rpm -qf /lib64/libkrb5.so.3.3
krb5-libs-1.18.2-22.fc33.x86_64
$ rpm -q libabigail
libabigail-1.7-2.fc33.x86_64

The fact that these are reported even as harmless changes to the ABI even when
they are an identity indicates that the ABI is not being fully represented in
the abidw file generated by abidw.
