--- Comment #2 from Mark Wielaard <mark at klomp dot org> ---
That is interesting, it seems to occur because the section is decompressed
twice (and fails). Apparently elf_getdata leaves some uninitialized data around
the first time, which gets picked up (and checked) the second time.
This can only happen when using elf_compress_gnu because we cannot tell whether
or not the data is already (de)compressed (it is a convention based on the
section name, instead of using a proper section flag).
It can also be triggered on the second example with valgrind eu-readelf -w
