--- Comment #5 from Sergei Trofimovich <slyfox at gcc dot gnu.org> --- Comparing example file: $ LANG=C cmp --ignore-initial=16 ./stage2-x86_64-pc-linux-gnu/libgomp/task.o ./stage3-x86_64-pc-linux-gnu/libgomp/task.o ./stage2-x86_64-pc-linux-gnu/libgomp/task.o ./stage3-x86_64-pc-linux-gnu/libgomp/task.o differ: char 325521, line 4234 Looks like there is slight non-determinism in .debug_loc. Don't know if it comes from gcc or binutils. Both wibbly entries are the same symbol offset: $ diff -U10000 <(x86_64-pc-linux-gnu-readelf -a stage2-x86_64-pc-linux-gnu/libgomp/task.o) <(x86_64-pc-linux-gnu-readelf -a stage3-x86_64-pc-linux-gnu/libgomp/task.o) | egrep 'section|^[-+]' Relocation section '.rela.debug_loc' at offset 0x36938 contains 7185 entries: -00000000e312 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 -00000000e320 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000e312 000200000001 R_X86_64_64 0000000000000000 .text + 66cd +00000000e320 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000e6f5 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 -00000000e703 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000e6f5 000200000001 R_X86_64_64 0000000000000000 .text + 66cd +00000000e703 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000e9c4 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 -00000000e9d2 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000e9c4 000200000001 R_X86_64_64 0000000000000000 .text + 66cd +00000000e9d2 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000ec69 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000ec69 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000eecd 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000eecd 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000ef61 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000ef61 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000f01f 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000f01f 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -00000000f388 000200000001 R_X86_64_64 0000000000000000 .text + 66b8 +00000000f388 000200000001 R_X86_64_64 0000000000000000 .text + 66cd -0000000112e3 000200000001 R_X86_64_64 0000000000000000 .text + 5a84 +0000000112e3 000200000001 R_X86_64_64 0000000000000000 .text + 5a79
