Yes unfortunately, nothing I have willingly enabled, but I found traces of LTO in C++. C++ is used to link the final qemu-system binary and on my system c++ has LTO: c++ -v Using built-in specs.

I will find a way to disable this thing and will correct the patch accordingly. Thanks a lot, and sorry for the inconvenience! Claudio
