From 31694084eb47127edb38d854b3d762b6a870985d Mon Sep 17 00:00:00 2001 From: Mark Dilger Date: Tue, 28 Jan 2020 15:25:58 -0800 Subject: [PATCH] WIP patch to demonstrate problem Apply and run 'make check' to see the problem. I've created an empty expected output file, just to keep the regression test infrastructure happy.
