           Summary: ICE
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: vivekrao4@yahoo.com


For the code 

module random_integer_mod
implicit none
contains
function vec_block(ivec,block_size) result(jvec)
integer, intent(in) :: ivec(:)
integer, intent(in) :: block_size
integer             :: jvec(size(ivec)*block_size)
jvec = 1
end function vec_block
!
function permute_blocks(nitems,block_size) result(ivec)
integer, intent(in)  :: block_size,nitems
integer              :: ivec(nitems)
integer              :: nblocks
integer, allocatable :: jvec(:)
nblocks = 1
allocate (jvec(nblocks*block_size))
jvec = vec_block(permutation(nblocks),block_size)
ivec = 1
end function permute_blocks
!
function permutation(n) result(ivec)
integer, intent(in) :: n
integer             :: ivec(n)
ivec = 1
end function permutation
end module random_integer_mod

Works here with 4.6.0 20101211 on x86-64-linux (also under valgrind).

I can't confirm this ICE. My gcc is 4.6.0 20101215. Maybe this issue was
already fixed.
