--- Comment #11 from Mark Wielaard <mark at klomp dot org> ---
Note that there are multiple warnings in that log:

warning: Unsupported auto-load script at offset 0 in section .debug_gdb_scripts

Use `info auto-load python-scripts [REGEXP]' to list them.

dwz: Allocatable section in
./usr/bin/boottime-0-0.3.20200615git15668db.fc33.x86_64.debug after
non-allocatable ones

It is a golang binary and seems to use both the golang linker and the system
linker. I suspect that it really is slightly corrupt because of that.

Note that the section offsets jump around a bit:

In particular .intrp (25), .note.gnu.build-id (26) and .note.go.buildid (27)
have offsets that place them at the start of the file instead of at the end.
