           Summary: [4.6 Regression] reallocation of array during
                    constructor assignement
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: xarthisius.kk@gmail.com


Assigning [...] constructor to allocatable array changes size of that array, if
size([...]) is not equal to size(array)

program ala
   implicit none
   integer, dimension(:), allocatable :: ivec

   allocate(ivec(3));  write(*,*) shape(ivec)
   ivec = [1,2];       write(*,*) shape(ivec) !!!!!!

end program ala
