[Bug fortran/38095] character ICE

[burnus at gcc dot gnu dot org]

------- Comment #10 from burnus at gcc dot gnu dot org  2008-11-12 23:42 -------
Some debugging shows that sym->name is "same" and sym->attr.function == 1.
Furthermore is arg1->expr_type == EXPR_FUNCTION and arg1->ts.cl->length ==
NULL.

(For cross referencing: http://gcc.gnu.org/ml/fortran/2007-12/msg00160.html is
the mail to the patch which added the TODO line.)

Using the following patch and calling xmain, the program prints
"size(labels)= 1".
