From 87f746b40b11531cf25fbbfb7ac33d6e8e03a279 Mon Sep 17 00:00:00 2001 From: Micael Karlberg <bmk@erlang.org> Date: Wed, 1 Jun 2022 20:08:55 +0200 Subject: [PATCH 5/7] [erts|inet-drv] Fixed debug printout The printout cound not be done in some cases. There was a driver_exit call in some cases. If that was the case the debug printout could not be done, since it used the debug flag (among other things).
