Well, this is embarrassing.

I repeated all my steps again on my development laptop (Fedora 30, GCC 9.1.1, glibc 2.29.15) and it all works (doesn't
segfault,can initdb). 

On my Amazon Linux EC2 , (gcc 7.3.1, glibc 2.6.32) it exhibits fault on patched version.

Same steps, same sources.

Got to be build tools/version related on my EC2 instance.

Darn it. Sorry for wasting your time, I will continue to evaluate patch, and be mindful that something, somewhere is
sensitiveto build tools versions or lib versions. 

Many regards
