It's in a switch statement somewhere.
It sounds as though this is a bug which involves multiple files, so
it'll be difficult to reduce it.
If you're able to compile DMD, change this line in statement.c line 2620:
Statement *SwitchStatement::semantic(Scope *sc)
{
//printf("SwitchStatement::semantic(%p)\n", this);
tf = sc->tf;
+ if (cases) error("xxx");
assert(!cases); // ensure semantic() is only run once
and then you'll get the line number where the error is.
Yay for first time compiling dmd :)
Sorry you had to do that!
If you can provide the function which contains the switch statement,
there's a chance I could reproduce it.
I've got something better.. a minimal version :)
Which even crashes through bud.
Awesome!
I'll track this sucker down so it doesn't hit anyone else.

module main;
enum E { A = 0 };
struct S{
int i;
static S func( S s, E e ){
switch( e ) //<---------- here
{
default:return s;
}
}
static const S s_def = { 1 };
//static const S A = func(s_def, E.A ); // forward reference error + crash
//static const S[1] ARR = [ E.A : func(s_def, E.A )]; // error : xxx + crash
}
void main(){}

To test all this I switched from 1.065 to 1.066; just to make sure it hadn't
been
fixed already.
And now my project won't compile any more even though bud+1.065 will happily do
so..
bud+ 1.066 gives me the following (no crash though)

Internal error: backend\cgobj.c 2424
What does that mean?
The DMD makefile compiles in debug mode by default. It prints some
useless 'fixups' junk. You need to compile with make -fwin32.mak release
or make -flinux.mak release
to make a release compiler. But, not important, you can go back to using
an official compiler again. <g>
The internal error means it's now crashing in the backend, rather than
the frontend. Not an improvement!
