--- Comment #1 from anlauf at gcc dot gnu.org ---
Note that
pack( [ (k, k = 1,max_sum)], &
[ ( count( [((i**3+j**3, i = 1,j), j = 1,max_ij)] == k ) > 1, k = 1,max_sum )]
)
is a constant expression that the frontend tries to simplify at compile time.
I assume that most of the time goes into handling of the array constructors.
There's no limit implemented that checks the complexity of such expressions
and to give up if that limit is reached.
An expression like the above could occur in a parameter definition, and a
limit then might terminate the compilation with an error.
Fortunately, you've already found a workaround.
