[Bug c/39900] New: ICE on nested function returning pointer to VLA

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

int a;
void
f (void)
{
  int (*g (void))[a] { return 0; }
}

gets an ICE:

t.c: In function 'f':
t.c:5: internal compiler error: in put_pending_sizes, at stor-layout.c:108
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Unlike bug 21374, this is returning a pointer to a VLA rather than
a variable-size type itself.

If a typedef is used for the VLA, it does not ICE.

int a;
void
f (void)
{
  typedef int T[a];
  T *g (void) { return 0; }
}
