From 183083c35972611e7786c7ee0c96d7da571631ed Mon Sep 17 00:00:00 2001 From: Carlos O'Donell Date: Wed, 29 Apr 2020 16:31:29 -0400 Subject: support: Set errno before testing it. In test-conainer we should set errno to 0 before calling strtol, and check after with TEST_COMPARE. In tst-support_capture_subprocess we should set errno to 0 before checking it after the call to strtol. Tested on x86_64.
