I was also able to reproduce this with the attached Python program and
psycopg2 package.
Steps to reproduce:
1. Install libpq for PostgreSQL 12:
brew install postgresql(at)12
2. Install the psycopg2 package:
pip install psycopg2
3. Start a PostgreSQL server:
docker run --rm -d -p 127.0.0.1:5432:5432 postgres:12
4. Execute some GSS path before and after fork:
python macos-gss-crash.py
It generates a crash report and prints:
main ok
-11
In this and the previous tests I can avoid/workaround the segfault by
specifying gssencmode=disable.
Thanks!
Chris
