From 4feeb9d5f82229bf39621be755bda81521539476 Mon Sep 17 00:00:00 2001 From: Li Zhijian Date: Mon, 25 Oct 2021 11:26:58 +0800 Subject: refscale: Always log the error message An OOM is a serious error that should be logged even in non-verbose runs. This commit therefore adds an unconditional SCALEOUT_ERRSTRING() macro and uses it instead of VERBOSE_SCALEOUT_ERRSTRING() when reporting an OOM.
