In the compiler, any call to optimize() may create an ErrorExp, if an array
bounds error occurs. This error is currently not propagated by any of the
optimize() functions. If this optimized expression is passed to CTFE, the CTFE
check for AST validity will fail.

Here's a single static assert which tests 14 cases.

int global;
static assert((((((([5,5][3] + global -
global)*global/global%global)>>global)&global|global)^global) == 9, [2,3][17])
|| ([3,3,3][9] is 4) && ([[1,2,3]][4]).length);
