      objcopy changes entsize of .relro_padding section generated by lld, which may break processing by other tools (in particular eu-strip). The overall effect is that debuginfo extraction by find-debuginfo may fail on lld-generated artifacts on the i686 architecture.

      This has been fixed in upstream binutils in commit 88141209e25ce19473ec07d7aac09cc68f06a630.

      Issue can be reproduced by running objcopy on the shared object https://drive.google.com/file/d/1Wpju3kKq2-U0BX7NoJ2KFL6hVF494kZJ/view?usp=sharing. Then readelf --section-headers will print

      [24] .relro_padding    NOBITS          02521d2c 251fd2c 0002d4 08  WA  2   0  1

      instead of

      [24] .relro_padding    NOBITS          02521d2c 251fd2c 0002d4 00  WA  0   0  1
