From 6d9878cc60ba97fc99aa92f40535644938cad907 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 13 May 2008 04:45:56 -0400 Subject: [PATCH] clone: bsd shell portability fix When using /bin/sh from FreeBSD 6.1, the value of $? is lost when calling a function inside the 'trap' action. This resulted in clone erroneously indicating success when it should have reported failure. As a workaround, we save the value of $? before calling any functions.
