From e814dffcc9810ed77fe99081be9751b620a894c4 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Thu, 20 Aug 2015 16:00:38 -0700 Subject: qemu-img: Fix crash in amend invocation Example: $ ./qemu-img create -f qcow2 /tmp/t.qcow2 64M $ ./qemu-img amend -f qcow2 -o backing_file=/tmp/t.qcow2, -o help \ /tmp/t.qcow2 This should not crash. This actually is tested by iotest 082, but not caught due to the segmentation fault being silent (which is something that needs to be fixed, too).
