From 76713be0f593d7b6cea0696024b804888a61547a Mon Sep 17 00:00:00 2001 From: Alex Richardson Date: Fri, 29 Jan 2021 09:29:26 +0000 Subject: [PATCH] Avoid double output in fenv_test This tests fork()s, so if there is still data in the stdout buffer on fork it will print it again in the child process. This was happening in the CheriBSD CI and caused the test to complain about malformed TAP output.
