Oh yeah, the code that kills gfortran is like this:

integer(C_INT8_T), parameter :: IBITC(0:65535) = [( &
ibits(i,0,1)+ibits(i,1,1)+ibits(i,2,1)+ibits(i,3,1)+ &

ibits(i,12,1)+ibits(i,13,1)+ibits(i,14,1)+ibits(i,15,1), &
i=0,65535)]

Maybe a stack overflow trying to store the whole thing.

How about as a DATA statement instead of PARAMETER?

This reminds me of limits on the size of static arrays with a
C compiler on the Alpha. (Probably the DEC compiler, though it
might have been gcc.)
