Package: gfortran
Version: 4:4.7.2-1
Severity: normal
Dear Maintainer,
The code below leads to segmentaion fault:
program allocatables
implicit none
integer, parameter :: CH_ = 4
type with_character
character(kind=CH_) :: Post = CH__" "
integer :: i = 0
end type
type with_string
character(4, kind=CH_) :: Post = CH__" "
integer :: i = 0
end type
type(with_character) :: CharList(10)
type(with_string) :: StringList(10)
type(with_character), allocatable :: CharAlloc(:)
type(with_string), allocatable :: StringAlloc(:)
CharAlloc%Post = CharList%Post
CharAlloc = Pack(CharAlloc(2:), .true.) ! First segmentation fault.
StringAlloc%Post = StringList%Post
StringAlloc = Pack(StringList(2:), .true.) ! Second segmentation fault of
another type.
end program allocatables
=========================
First segmentation fault:
malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *)
&((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct
malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size)
>= (unsigned long)((((__builtin_offsetof (struct malloc_chunk,
>fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t)))
>- 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end &
>pagemask) == 0)' failed.
Program received signal SIGABRT: Process abort signal.
