Ugh. I have a patch that would allow a repeat count of
2**32-1. For this program:
program main
integer(kind=1), dimension(4294967294_8) :: i
data i /4294967294_8 * 1_1/
print *,i(1)
end program main
and 'gfc4x -o z -O p.f90', I see
51879 sgk 1 121 0 554M 554M RUN 1 5:48 92.24% as
in top(1). Do we really want to support this large of a repeat count?
