To make that explicit:
% cat gfcbug128c.f90
program gfcbug128c
integer(4) :: count_rate, count_max
call system_clock (count_rate=count_rate,count_max=count_max)
print *, count_rate, count_max
call system_clock (count_rate=count_rate)
call system_clock (count_max=count_max)
print *, count_rate, count_max
end
gfortran 5 gives:
1000 2147483647
1000000 2147483647
any other compiler:
1000 2147483647
1000 2147483647
I'd have a hard time to explain that to anybody.
