My reading is different and corroborates the Solaris ld warnings: * for SHT_NULL, the ELF gABI 4.1 is pretty explicit: p. 4-13, p.57: SHT_NULL This value marks the section header as inactive; it does not have an associated section. Other members of the section header have undefined values. * SHF_EXCLUDE is a later addition, also included in the Solaris Linker and Libraries Guide: http://docs.oracle.com/cd/E53394_01/html/E54813/chapter6-94076.html#OSLLGchapter6-10675 SHF_EXCLUDE This section is excluded from input to the link-edit of an executable or shared object. This flag is ignored if the SHF_ALLOC flag is also set, or if relocations exist against the section. This is identical to the wording in the binutils PR which introduced this flag: PR gas/11600: Support SHF_EXCLUDE https://sourceware.org/bugzilla/show_bug.cgi?id=11600 Seems far from clear to me that those are valid ELF objects: the warnings seem totally appropriate.
