Yep, something is wrong with LTO:
/hdd/uros/gcc-build/gcc/xgcc -B
/hdd/uros/gcc-build/x86_64-pc-linux-gnu/libsanitizer/ -B
/hdd/uros/gcc-build/x86_64-pc-linux-gnu/libsanitizer/asan/ -B
/hdd/uros/gcc-build/x86_64-pc-linux-gnu/libsanitizer/asan/.libs -B
/hdd/uros/gcc-build/gcc -fstack-protector-strong -fsanitize=address -O2 -flto
-save-temps pr64820.c
produces ccbxiIwG.ltrans0.s with:
movl $-235802127, 2147450880(%rdx)
movl $-202116109, 2147451396(%rdx)
>> movq 0, %rax
movq %rax, 4184(%rsp)
xorl %eax, %eax
Confirmed as LTO problem.
