When shared: true, write_shared_dynamic_sections unconditionally dereferences dynstr_section (and later dynsym_section). If a caller uses Writer.write! directly with an ELF object that lacks these sections (e.g., from Reader or a pre-change Builder), dynstr_section/dynsym_section will be nil and this will raise NoMethodError, preventing shared output. Consider guarding for missing sections or raising a clearer error so shared doesn’t crash on valid-but-minimal ELF inputs.
