            Bug ID: 3392836
           Summary: section.<secname>.start worse then label
           Product: NASM
           Version: 2.16.xx
          Hardware: PC
                OS: Linux
            Status: OPEN
          Severity: minor
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us

%iassign _org 0x01000000

section my_section align=1 start=_org+16 ; start = 0x01000010 i.e. 10 00 00 01
section_start_label: ; 0x01000010 i.e. 10 00 00 01
dd section_start_label
dd section.my_section.start
section_end_label: ; 0x01000018 i.e. 18 00 00 01
dd section_end_label - section_start_label ; 0x00000008 i.e. 08 00 00 00
; dd section_end_label - section.my_section.start ; error: expression is not
simple or relocatable
my_section_size equ section_end_label - section_start_label
dd my_section_size ; 0x00000008 i.e. 08 00 00 00
; my_section_size2 equ section_end_label - section.my_section.start ; error:
invalid operand type
; dd my_section_size2

; Anywhere section_start_label can be used, section.my_section.start is also
known and should just work. Maybe the assembler could create a ..@ label and
reference it as needed?
; using [section <secname>] does not fix this issue.
