--- Comment #1 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
With -fcoarray=single, the test case fails with

Program received signal SIGSEGV, Segmentation fault.
eval_intrinsic_f3 (op=INTRINSIC_MINUS, eval=0x615a60
<gfc_arith_minus(gfc_expr*, gfc_expr*, gfc_expr**)>, op1=0x0, op2=0x1d73140)
    at ../../trunk/gcc/fortran/arith.c:1700
1700      result = reduce_binary0 (op1, op2);
(gdb) p op1
$1 = (gfc_expr *) 0x0

This does not happen with 4.8, hence marking as regression.
