The object is clearly corrupted.
Thanks to your hint to readelf, I found out that it gets corrupted
during dump(8) (or resotore, not yet analyzed).
The obj tree contains the good version, the dump archive not.
The dump archive is used as source for the ISO, hence the described errors.
Now I have to dig in 10 years old deployment scripts to track down and
reproduce the corruption. No explanation so far, but for sure no
rtld-elf problem :-)
And also not a problem in the FreeBSD make chain, building stable/12 on
stable/11 works as intended and doesn't produce the mutilated
libcrypto.so.111!
Thanks,
