AXFR garbage in zone with eccentric RRtypes #7446
SIDN Labs runs a so called DNS workbench.
One of the zone files in that workbench contains a range of different RRtypes. We managed to load it successfully in PowerDNS by slaving it with a sqlite3 back-end (and earlier attempt to do it with a bind backend resulted in #7437)
The zone appears to work, but an AXFR fails:
dig AXFR types.wb.sidnlabs.nl @powerdns.sidnlabs.nl
Steps to reproduce
Successful zone transfer
; <<>> DiG 9.13.3 <<>> AXFR types.wb.sidnlabs.nl @powerdns.sidnlabs.nl
I can reproduce using 4.1.x, but this is fixed in 4.2, which will be released soon.
Please confirm using https://downloads.powerdns.com/autobuilt_browser/#/auth/4.2.0-rc1
See #6377 (although this PR does not seem to fix the MR case, it is fixed as well in my testing).
IMO this is not worth the trouble to backport since the record types are deprecated anyway.
