          Issue ID: 16574
           Summary: [REG 2.072.0-b1] Unexplained errors about functions
                    that overridde anything
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd

This problem appears only from DMD 2.072.0-b1 and under linux x86-64. You
should have the development version of x11, freetype and cairo to test
(otherwise you'll get linker errors, but that's not the point)

1. place you in a temporary folder
2. create a shell script with 

==========================
git clone https://github.com/BBasile/kheops.git
cd kheops/runnable
dub default_alignment.d
==========================

3. execute this script and you should get:

> ../src/kheops/control.d(1866,1): Error: class kheops.control.Control cannot implicitly generate a default ctor when base class kheops.control.CustomControl is missing a default ctor
> ../src/kheops/styles.d(28,5):        while looking for match for PublishedObjectArray!(Style)

4. (optional) Try 1/2/3 with 2.071.2: no problem (or just the linker messages).

Apologies for this unpleasant report but I cannot provide more simple.
