The error message is generated in
gfc_conv_array_ref
it's called via gfc_trans_where_3 - gfc_conv_loop_setup -
gfc_add_loop_ss_code - gfc_conv_variable
Thus, the condition (mask) ends up at
gfc_add_ss_to_loop

Ouch!
We need some sort of lazy evaluation.
Like (pseudo-code)
bool scalar_ever_evaluated = false;
whatever_type scalar_value;
while(1)
{
/* loop handling stuff */
if (scalar_ever_evaluated)
{

Confirm, the bounds checks are misplaces. Simplified test case:
implicit none
integer :: A(1), i,b(1)
logical :: mask(1)
mask = .false.
b = 5
do i = 2, 2
where (mask)
A = b(i)
end where
end do
end
If one
