Mandrill has been failing since this patch went in, eg

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=mandrill&dt=2017-03-25%2021%3A34%3A08

It doesn't seem to be a platform-specific problem: I can duplicate the
failure here by applying same settings mandrill uses, ie build with
-DRANDOMIZE_ALLOCATED_MEMORY and set force_parallel_mode = regress.

I doubt that the bug is directly in that patch; more likely it's
exposed a pre-existing bug in parallel logic related to triggers.
