Merging preproc.c fixes from 2.13.xx branch to 2.12.xx solved it.
Although, the output is not expected (with all nasm versions):

$ cat 1.asm
%define TEXT  _TEXT     align=1 public use32 class=CODE FLAT
%define DATA  _DATA     align=4 public use32 class=DATA FLAT
%define CONST CONST2    align=4 public use32 class=DATA FLAT

segment TEXT
segment DATA
segment CONST

$ nasm -E 1.asm
%line 4+1 1.asm

[segment _TEXT align=1 public use32 class=CODE FLAT]
[segment _DATA align=4 public use32 class=_DATA align=4 public use32 class=DATA
FLAT FLAT]
[segment CONST2 align=4 public use32 class=_DATA align=4 public use32
class=_DATA align=4 public use32 class=DATA FLAT FLAT FLAT]

I guess defining certain keywords makes it go haywire, so
my solution was changing the source like:
%define SEG_TEXT  _TEXT     align=1 public use32 class=CODE FLAT
%define SEG_DATA  _DATA     align=4 public use32 class=DATA FLAT
%define SEG_CONST CONST2    align=4 public use32 class=DATA FLAT

segment SEG_TEXT
segment SEG_DATA
segment SEG_CONST

... which does what is intended:
$ nasm -E 1.asm
%line 4+1 1.asm

[segment _TEXT align=1 public use32 class=CODE FLAT]
[segment _DATA align=4 public use32 class=DATA FLAT]
[segment CONST2 align=4 public use32 class=DATA FLAT]
