I ran into an SSL issue when using the MSYS2/MINGW build of Postgres
for the PgBouncer test suite. Postgres crashed whenever you tried to
open an ssl connection to it.

I'm wondering if the issue described in this thread could be related
to the issue I ran into. Afaict the merged patch has not been released
yet.
