The problem is in implicitConvTo() and implicitCastTo(). They call optimize(),
but don't save the result.
optimize() can generate an error message, and return an ErrorExp when an array
bounds error occurs.
It should be called BEFORE implicitConvTo, instead of inside it.
There are many cases of this, here are some examples:
void example()
{
char c = "abcdef"[17];
char[7] x = "abc"[12];
int ww = "abc"["afds"[9]];
}
diag.d(4): Error: string index 17 is out of bounds [0 .. 6]
diag.d(4): Error: string index 17 is out of bounds [0 .. 6]
diag.d(5): Error: string index 12 is out of bounds [0 .. 3]
diag.d(5): Error: string index 12 is out of bounds [0 .. 3]
diag.d(5): Error: string index 12 is out of bounds [0 .. 3]
diag.d(5): Error: string index 12 is out of bounds [0 .. 3]
diag.d(6): Error: string index 9 is out of bounds [0 .. 4]
diag.d(6): Error: string index 9 is out of bounds [0 .. 4]
