--- Comment #3 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
just wondering if this would also catch a Fortran testcase, which compiles into
malloc and memset:

MODULE M
  REAL*8, DIMENSION(:), ALLOCATABLE, SAVE :: data
  INTEGER, PARAMETER :: n=2**16
CONTAINS
  SUBROUTINE TEST
    ALLOCATE(data(n))
    data(:)=0
  END SUBROUTINE
END MODULE
