bug.d(7): Error: alias test0.a recursive alias declaration
Stack overflow

D1 only, worked in 1.061.
Doesn't happen if DMD is compiled in debug mode.

And this is nocompile/c/const_34_A.d, which is also failing. In total, 5 dstress cases are now hitting a stack overflow because of this bug. D2 is not affected.
const auto a = a;

Regression was introduced in 1.061 by the fix to bug 4016, in expression.c, DsymbolExp::semantic()
//printf("Identifier '%s' is a variable, type '%s'\n", toChars(),
v->type->toChars());
if (!type)
{
+ if (!v->type && v->scope)
+ v->semantic(v->scope);
type = v->type;
if (!v->type)
{ error("forward reference of %s %s", v->kind(), v->toChars());
The code doesn't fail on D2, because v->scope is not set on D2.

Patch for D1 - I'm not entirely sure on the correctness of the first hunk.

Yep, that questionable change broke tango build - should now be sorted.
