Log attached. I filled a bug report long time ago: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63907 It is still unconfirmed. I will try to build without libitm which will need some time. I'll back with a report after successful installation or failure. The log when compiling against 3.x kernel version: Making install in sanitizer_common make[3]: Entering directory
