            Bug ID: 3392823
           Summary: OMF object output format silently ignores vstart= for
                    sections
           Product: NASM
           Version: 2.16 (development)
          Hardware: All
                OS: All
            Status: OPEN
          Severity: normal
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us

I recently ported some sources from TASM to NASM, allowing to assemble either
with -f bin format or -f obj. I was surprised to find that -f obj accepted to
specify sections with vstart= but that had no effect on the actual output. I
understand that this is something the linker should implement rather than the
assembler. I do think NASM should warn or error out on this however.

In the NASM source, the OMF output format simply ignores unknown section
attributes:
