Here is a small code:
PROGRAM test
IMPLICIT NONE
INTEGER, PARAMETER :: wp=KIND(1.0d0)
REAL(wp), ALLOCATABLE, DIMENSION(:) :: rr
COMPLEX(wp), ALLOCATABLE, DIMENSION(:) :: cc
INTEGER :: n
n=1000000 !<= this value is OK
n=1100000 !<= this value causes error
ALLOCATE(cc(n))
cc=(1.0_wp, 1.0_wp)
ALLOCATE(rr(n))
rr(:)=REAL(cc(:), KIND=wp) !<= here is runtime error
! rr(:)=REAL(cc(:)) !<= it's OK
END PROGRAM
When I compile without any switch under ifort 16.0.2 program crashes. It runs well under -O3 optimization level and crushes under the
-O0, -O1 -O2 optimization levels.
It run well if one switch the working precision (wp) from DOUBLE PRECISION to SINGLE PRECISION (i.e. wp=KIND(1.0) )
Under ifort 16.0.1 everything is OK.
