it
backtrace from hanging (few minutes)

Sorry for the lack of detail, I'm not sure how to describe this properly ye=
t.

In Gentoo, we have tooling for developers to use abidiff when upgrading
packages or changing build options, which is a great convenience. It compar=
es
the system copy with the version just built. Thanks for libabigail, it's a =
huge
help.

With ghostscript-gpl-10.0.0, libabigail's abidiff seems to hang when doing =
this
comparison (had been running for an hour at this point):
```
root     2761321 97.6  1.8 1360832 1242480 pts/1 RN+  02:40  55:22 abidiff
--stats --d1 /usr/lib/debug --d2
/var/tmp/portage/app-text/ghostscript-gpl-10.0.0-r4/image/usr/lib/debug
/usr/lib64/libgs.so.10.00
/var/tmp/portage/app-text/ghostscript-gpl-10.0.0-r4/image/usr/lib64/libgs.s=
o.10.00
```

Same happens without --stats.

$ abidiff --version
abidiff: 2.2.0

Attached backtrace after running for about 3-4 minutes on a fresh run. Sorry
it's not from a longer run, I can grab one of those if needed. Let me know =
if &
how to grab more info. Thanks!
