We weren't dereferencing the variable, so this should have been safe. However, it isn't clear in the C and C++ standards whether it legitimately was safe. So let's just fix it. ``` simplereader.c:180:9: warning: pointer ‘buf’ may be used after ‘free’ [-Wuse-after-free] simplereader.c:177:5: note: call to ‘free’ here ``` Signed-off-by: Thiago Macieira <thiago.macieira@intel.com>
