            Bug ID: 34750
           Summary: lld produces a corrupted file header
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org

Given

test.s:
 .section .zed, "a"
 .zero 4

test.script:

PHDRS {
  foobar PT_LOAD FILEHDR PHDRS;
}
SECTIONS {
  . = 0x1000;
  .abc : { *(.zed) } : foobar
}

with test.s assembled for x86_64-pc-linux and linking with

ld.lld --script test.script test.o -o t

the file header is corrupted:

% file t
t: data

This works with bfd, gold and lld before r311586
