[Bug fortran/25746] New: Elemental assignment gives wrong result

[anlauf at gmx dot de]

Hi,

now that elemental subroutines appear to not ICE anymore,
I found that the example code at

http://home.comcast.net/~kmbtib/Fortran_stuff/elem_assign.f90

gives a wrong result.

gfortran prints:

 original x =            7          11          13
 permuted x =           11          13           7
      new x =           11          13          11

However, the last line should equal the second.  It appears that
the assignment

   x = x((/2,3,1/))

does not properly recognize that source and target overlap.

Cheers,
-ha
