Summary: ELF incorrect size following --strip-sections
Product: tools
Version: trunk
Hardware: PC
OS: Windows NT

Severity: normal
Priority: P

--strip-sections should leave an ELF with only its ELF header and program
header contents. The ELFWriter<ELFT>::totalSize() function incorrectly
calculates the size of the ELF however in this case: if WriteSectionHeaders is
false, it includes enough space to write the section headers (but not the null
section header for some reason...!)
