Defining an -f obj global label in terms of an equate equal to an extern label doesn't emit any error, warning, or useful definition in the object file

[ecm-pushbx]

I expect this to not fail silently:

test$ cat test.asm 

        section code
extern extlabel
global globlabel
globlabel equ extlabel

omfdump is the tool from https://github.com/boeckmann/omfdump

As visible, NASM emits two EXTDEF subrecords, but it doesn't (and probably cannot) usefully define the one label in terms of the other. I want a warning or error message about this fact.

I wrote about this error in https://pushbx.org/ecm/dokuwiki/blog/pushbx/2026/0309_early_march_work_on_ldebug_warplink_ident86_and_patchini

lDebug

Duplicate some equates (eg). NASM won't generate a definition in the object file when trying to define a global label in terms of an equate that references an extern label. (The fact that it silently fails is concerning.)

Perhaps you could give some advice what should happen?

[ecm-pushbx]

An error or a warning.
