Description

openSUSE just enabled LTO by default for its packages in Tumbleweed/Factory.
https://lists.opensuse.org/opensuse-factory/2019-07/msg00240.html
https://gcc.gnu.org/wiki/LinkTimeOptimization

This means the distro provided CFLAGS now changed from

without LTO

CFLAGS='-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection  -g'

to

with LTO enabled

CFLAGS="-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -flto=4 -g -Werror=implicit -Werror=maybe-uninitialized -Werror=memset-transposed-args -Werror=null-dereference -Werror=sizeof-array-argument -Werror=sizeof-pointer-memaccess" 

compiling openbsc master then triggers the following warnings/errors:

[   23s] gsm_04_08.c:1464:2: error: 'mi_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
