It would be useful if we're able to use it. Could you use
https://dovecot.org/tools/core-tar.sh
<https://dovecot.org/tools/core-tar.sh> to send the core and the related
binaries (e.g. just email to me)? The usage is explained at the beginning of the
script. At least in theory we could then debug with the core file, although
I've had some trouble even then.

But just in case the core doesn't work, could you also do:

fr 8
p *((struct doveadm_connection *)io->context)
p *((struct doveadm_connection *)io->context)->input
