           Summary: new enum struct re-allocated at compile time

DMD 2.052, this gives an Assertion failure:


struct Foo {
    this(int) {}
}
enum Foo* f = new Foo(0);
void main() {
    assert(f == f); // Assertion failure
}


In my opinion this needs to become a compile-time error, or the assert needs to pass.

Enum associative arrays have a similar problem.

------------------

The asm:

_D4test3Foo6__ctorMFNciZS4test3Foo  comdat
      enter 4,0
      leave
      ret 4

__Dmain comdat
L0:   push 1
      mov EAX,offset FLAT:_D20TypeInfo_PS4test3Foo6__initZ
      push EAX
      call near ptr __d_newarrayT
      add ESP,8
      push 0
      mov EAX,EDX
      call near ptr _D4test3Foo6__ctorMFNciZS4test3Foo
      push EAX
      push 1
      mov ECX,offset FLAT:_D20TypeInfo_PS4test3Foo6__initZ
      push ECX
      call near ptr __d_newarrayT
      add ESP,8
      push 0
      mov EAX,EDX
      call near ptr _D4test3Foo6__ctorMFNciZS4test3Foo
      mov EDX,EAX
      pop EAX
      cmp EAX,EDX
      je L44
      mov EAX,6
      call near ptr _D4test8__assertFiZv
L44:  xor EAX,EAX
      ret

_D4test8__assertFiZv comdat
L0:   enter 4,0
      push EAX
      mov ECX,offset FLAT:_D4test12__ModuleInfoZ
      push ECX
      call near ptr __d_assertm
      leave
      ret

Is the same problem with associative arrays in another bug report?

> Is the same problem with associative arrays in another bug report?

The general bug, which includes AAs, was fixed with this commit:

https://github.com/donc/dmd/commit/fc67046cf1e66182d959309fb15ef9e2d4c266b9

The only thing which was unique to this one is the use of 'new'.
