Just for future newcomers, the answer for the above was given 
here:

By Adam D. Ruppe:

"
Try:

auto arr = new int[](size.width*size.height*3+1);

The int[x] syntax declares a statically sized array - statically 
sized meaning it must be known at compile time and thus cannot be 
variables, along a few other differences.

The new array syntax though returns one of variable size.
