If you can detect that the shdrs aren't valid then zeroing them out is the right thing to do. There are a couple of places in libdwfl that will try to use them instead of phdrs if the exist (also because, at least for debuginfo files, phdrs might not be trusted). For example dwfl_module_build_id () might not be able to find the build-id if it sees a corrupt shdr for the main ELF file. Cheers, Mark
