           Summary: dmd generate wrong end record, and linker doesn't check
                    this checksum
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: davidl@126.com


the end record of OMF obj file generated by DMD is:
8a 0200 0000

while the checksum is wrong, it should be 0x74, and the linker doesn't check this

The checksum value emitted is 0, which is a valid value meaning "ignore the checksum", which is why the linker ignores it.

The checksum serves no useful modern purpose, as obj files are not on easily corrupted media anymore like paper tape or crummy analog phone lines. Also, generating and checking the checksum slows down compilation speed.

So, it isn't done, by design. It isn't broken.
