Bug 10280 – CTFE: Circular variable initializers should be detected properly

Currently, when the initializer for a variable accesses that variable in CTFE, it's only indirectly detected via the 'recursion limit exceeded' message. It should be detected directly. --- const int q = foo(); int foo() { return q; } --- rr.d(3): Error: function rr.foo CTFE recursion limit exceeded rr.d(1): called from here: foo() rr.d(3): 1000 recursive calls to function foo rr.d(3): while evaluating q.init rr.d(1): called from here: foo()
