Hello Matthias, Thanks for your feedback
libvirt-python contains several extensions: libvirtmod, libvirtmod_qemu, libvirtmod_lxc those extensions use common source files (typewrappers.c, libvirt-utils.c) The fact that we enable parallel build and the build of all extensions are done in the same folder might lead to race condition that can lead to undeterministic output of the build Right now, enabling -lto seems to increase the occurrence of this race condition but I am not surprised if that happens in other conditions.
