     5                                  %endrep         ; line 5
     3                              <1> 
     4 00000000 26                  <1>  db 26h
     5                              <1> 
     6 00000001 26                  <1>  db 26h
     7                              <1> 
     8 00000002 26                  <1>  db 26h
     6                                                  ; line 6
$ 


Note how the first iteration's db is listed as line 4 (matching the true source
line from where the %rep content is defined), but the subsequent iterations
list db as line 6 and 8 respectively. After the %rep is done processing, the
line number correctly resets to 6.

In older NASM, the line number stays at that of the %endrep line:
