Bug 11756 – Irrelevant variable name printing in CTFE error message

This code will correctly fail to CTFE at line 5, but printed error message is weird. struct Ptr { void opAssign(Ptr other) { (*cnt)--; // Line 5 cnt = other.cnt; (*cnt)++; } size_t *cnt; } union Foo { size_t *ptr1; Ptr ptr2; } bool test() { Foo foo; size_t cnt = 1; foo.ptr1 = &cnt; size_t n; foo.ptr2 = Ptr(&n); assert(cnt == 0); return true; } static assert(test()); Output: test.d(5): Error: cannot read uninitialized variable ptr1 in CTFE <-- ptr1? test.d(24): called from here: foo.ptr2.opAssign(Ptr(& n)) test.d(29): called from here: test() test.d(29): while evaluating: static assert(test()) Expected error message for line 5 is: test.d(5): Error: cannot read uninitialized variable cnt in CTFE <-- cnt
