--- Comment #1 from Sergei Trofimovich <slyfox at inbox dot ru> ---
objtool is a part of linux kernel:
=20=20=20
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/too=
ls/objtool

Attached b.tar.gz contains:
- objtool binary
- object files before and after mangling with objtool

Note the .debug_info offset and alignment change:

$ readelf -a rapl.o.back > pre
$ readelf -a rapl.o > post
$ diff -U 0 pre post

-  [ 4] .debug_info       PROGBITS         0000000000000000  00000047
-       000000000000003c  0000000000000000   C       0     0     1
+  [ 4] .debug_info       PROGBITS         0000000000000000  00000048
+       000000000000003c  0000000000000000   C       0     0     8

My wild guess is that section's start is not adjusted correctly.
