This appears to have been fixed at some point, as I cannot reproduce it
anymore:

$ dmd t.d 
t.d(6): Error: function `t.A.m()` conflicts with previous declaration at t.d(2)
t.d(16): Error: function `t.B.m()` conflicts with previous declaration at
t.d(12)
$ ldc t.d 
ldc2               ldc-build-runtime  ldc-profdata       ldc-prune-cache    
$ ldc2 t.d 
t.d(6): Error: function `t.A.m()` conflicts with previous declaration at t.d(2)
t.d(16): Error: function `t.B.m()` conflicts with previous declaration at
t.d(12)
$ gdc t.d 
t.d:6:11: error: function ‘t.A.m()’ conflicts with previous declaration at
t.d:2:9
    6 |     float m() {
      |           ^
t.d:16:9: error: function ‘t.B.m()’ conflicts with previous declaration at
t.d:12:9
   16 |     int m() {
      |         ^


Same with global functions.
