These kinds of issues are always difficult to debug. There have been a couple of patches to stabilize different sorts which I don't think are in 4.3.3. That could conceivably cause differences if address space randomization is turned on. I don't know of any specific bug reports, though. In any case, try turning off address space randomization (/proc/sys/kernel/randomize_va_space). > finally, I compared langhooks1.o langhooks2.o >>cmp -i 16 langhooks1.o langhooks2.o > langhooks1.o langhooks2.o differ: byte 76626, line 514 Try running your commands with the --save-temps options and compare the resulting .s files.
