Bug 6053 – [CTFE] Two ICEs involving pointers (dereference and assign; pointer variable on stack)

Test case 1: ---------------- static assert({ int* a; return true; }()); ---------------- Assertion failed: (isStackValueValid(newval)), function createStackValue, file interpret.c, line 4070. Abort trap ---------------- Test case 2: ---------------- static assert({ int a; *(&a) = 0; return true; }()); ---------------- CTFE internal error: unsupported assignment *& a = 0 Assertion failed: (e1->op == TOKarraylength || e1->op == TOKvar || e1->op == TOKdotvar || e1->op == TOKindex || e1->op == TOKslice), function interpretAssignCommon, file interpret.c, line 2380. Abort trap ---------------- (In 2.052 this simply result in a "cannot evaluate" error, not an ICE.) A related test case of #2 would be ---------------- static assert({ int a, b, c; (c ? a : b) = 1; return true; }()); ---------------- This causes an ICE because (c ? a : b) is rewritten to *(c ? &a : &b).

These codes are actually made CTFE-able. Oh well. https://github.com/D-Programming-Language/dmd/commit/c1ae91d4149122daeab67fe76a0fe1e77cf30b79
