Yes, please do. And if that fails, is is realistic to test without those additional extensions? If not, where's their source?
So yes, I just reproduced the same assert abort on 10.7, so issue is still there.
I still need pg_fact_loader, but I was able to strip out any custom C code from the test and I am still able to produce the crash. I dropped extensions pgl_ddl_deploy and pglogical_ticker. pg_fact_loader can optionally use a pg background worker, but I am bypassing that and thus only running plpgsql functions, and still producing the crash. This makes me doubt that it could have anything to do with these extensions.
