Bug 24483 – Lack of error report from compiler - not linker one

abstract class A { abstract void foo(); } class B : A { final override void foo() { super.foo(); // Should report an error on this line } } void main() { auto b = new B(); } Get obscured below error message ./onlineapp.d:10: error: undefined reference to '_D9onlineapp1A3fooMFZv' collect2: error: ld returned 1 exit status Error: linker exited with status 1

What compiler version are you using? I'm using 2.107 and I get: test.d(10): Error: call to unimplemented abstract function `void foo()` test.d(10): declared here: test.d(3) Seems it was fixed in: https://github.com/dlang/dmd/pull/15652

From this website: https://run.dlang.io/?compiler=dmd with -v option, it has output "version v2.105.3" Look like it needs and update to latest release
