[Bug fortran/45744] New: internal compiler error: in gfc_conv_expr_op, at fortran/trans-expr.c:1366

[jpr at csc dot fi]

Hi,

the following fortran code hits an assert() in fortran/trans-expr.c:1366

MODULE m
CONTAINS
  FUNCTION rnd(n)
    INTEGER, INTENT(in) :: n
    REAL(8), DIMENSION(n) :: rnd
    CALL RANDOM_NUMBER(rnd)
  END FUNCTION rnd

  SUBROUTINE GeneticOptimize(parsize )
    INTEGER :: parsize

    REAL(8) :: popcross=0
    LOGICAL, ALLOCATABLE :: mask(:)

    allocate(mask(parsize))
    mask = (rnd(parsize) < popcross)
  END SUBROUTINE GeneticOptimize
END MODULE m
