We get an ICE now:
t.f90:26: internal compiler error: in gfc_trans_arrayfunc_assign, at
fortran/trans-expr.c:2632

While the original problem seems to have been fixed, we have a regression here:
if we comment out the line marked as "this works" everything compiles fine and
we get an executable that works (doesn't segfault), if we comment out the line
"this doesn't" instead, the compiler triggers the assertion Andrew pointed to.

Is anyone considering approving (or disapproving) Eriks patch? It would also
clear PR 25262 (tested), except for the part that EXTERNAL keyword propably
should not be allowed for procedures with INTERFACE.

------- Additional Comments From tobi at gcc dot gnu dot org  2004-12-08 23:58 -------
For the second call we generate:
      atmp.12.dtype = 281;
      atmp.12.data = 0B;
      atmp.12.offset = 0;
      atmp.12.dim[0].stride = 0;
... (no changes to atmp.12
      funname (&atmp.12, (int4 *) n, &atmp.16);
which is clearly not correct, as atmp.12 should point to y (as it correctly does
in the first call).
