Product: D
Version: D2
Platform: Other
OS/Version: Mac OS X

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).
