Build fails with LTO
I tried to build with the following *FLAGS to optimize the build: -flto=4 -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing.
I got this error when building the testsuite binaries:

However I cannot tell whether the tests fail on the newer version as I cannot build it. :D
I have tried compiling the current libnetconf2 in devel (requires libyang devel) with the flags you posted and it worked fine. So please post the exact commands to reproduce this, otherwise I cannot help.
