This patch fixes a segfault when using the PUT
argument of RANDOM_SEED. There, however, is a
major problem with the current PRNG. This
simple program appears to trigger an alarmingly
bad sequence of numbers.
program s
integer, allocatable :: a(:)
integer i,n
real x(10)
call random_seed(size=n)
allocate(a(n))
a = (/ (i, i = 1, n) /)
call random_seed(put=a)
call random_number(x)
do i = 1, 10
print '(I2,2X,E15.6)', i, x(i)
end do
end program s

* random.c (random_seed): Use correct variable.
