From 7aa4a871afdfe946b8934f7761e8d4421b1102c6 Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Mon, 27 Sep 2021 14:07:18 -0700 Subject: [PATCH] ionic: fix gathering of debug stats Don't print stats for which we haven't reserved space as it can cause nasty memory bashing and related bad behaviors.
