Bug #: 54788
Summary: ICE on pointer-array element assignment
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sla...@staszic.waw.pl
Hello,
I'm sending below a short code causing an ICE of gfortran.
HTH,
Sylwester
P.S. BTW, could you help me in understanding the following error message:
$ cat question.f90
program question
type :: arr_t
real, pointer :: arr(:,:)
end type
class(arr_t), pointer :: vec(:)
allocate(vec(2))
allocate(vec(0)%arr(4,4))
vec(1) => vec(0)
end
$ gfortran question.f90
question.f90:8.2:
vec(1) => vec(0)
1
Error: Expected bounds specification for 'vec' at (1)
In principle, I'm trying to define a vector of pointers to arrays, and make two
elements of this vector point to the same array.
----------------------------------------------------------------------
$ cat bug.f90
program bug
integer, pointer :: a(:)
integer :: b
allocate(a(0:0))
a(0:0) => b
end
$ /usr/lib/gcc-snapshot/bin/gfortran bug.f90
f951: internal compiler error: Segmentation fault
