Nope..... https://smedley.id.au/tmp/bind-9.11.37-os2-20240704.zip should fix...

Backstory is I have some stub ipv6 stuff to get some things compiling - seems this  includes a definition of IN6PKTINFO - which is used despite named being built with ipv6 support disabled...

I'll look into the creation of a bind-os2 repo in github when I get time. We're about to head away for a week or so. This build should also fix the ascii/binary issue you  reported.

Thanks for investigating!

Cheers,

Paul
