Thank you for the report. Please recompile and 
*attach* the logfiles and 
paste the emerge info as described on
https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket
The logs must be part of the ticket, but not on external websites.
We need to have all information at hand before ticket assignment, so that the maintainer can look after it in one session with minimal number of callbacks.
Please reopen this ticket (Status:unconfirmed) afterwards.

Some gcc9 related fixes are in the staging branches, but seems incomplete:

Seems like this patch allows to build it:
