[Bug fortran/34429] Fails: character(len=use_associated_const) function foo()

[burnus at gcc dot gnu dot org]

------- Comment #4 from burnus at gcc dot gnu dot org  2008-01-17 17:26 -------
For cross reference the commit patch was:
http://gcc.gnu.org/ml/fortran/2008-01/msg00197.html

Besides the previously mentioned problems, there is also the following:

 gfc_clear_ts (gfc_typespec *ts)
[...]
+  if (ts->kind != -1)
+    ts->kind = 0;

This causes a problem if *ts is uninitalized, which happens for instance in
intrinsic.c's add_conv:

  gfc_typespec from, to;
[...]
  gfc_clear_ts (&from);

Assume now that the uninitialized memory contains "-1" ...
(Found using valgrind which has dozens of warnings of the type "jump depends on
uninitialized memory".)
