janus at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |janus at gcc dot gnu.org --- Comment #7 from janus at gcc dot gnu.org --- I think it is indeed expected for valgrind to report leaks for the code in comment 5, since variables in the main program are not supposed to be auto-deallocated in F08. Valgrind does not show any leaks if I put x into a subroutine: type :: thytype integer(4), allocatable :: h(:) end type thytype type :: mytype type(thytype), allocatable :: q(:) end type mytype contains subroutine s type (mytype) :: x x = mytype ([thytype([555])]) end subroutine end One should check the test cases listed in comment 0, in order to see if they still show leaks and if those are actual bugs.
