--- Comment #1 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> ---
This testcase:
--------------------------------------------------------------
int res, a, b;
void *foo;
static void f2 (int arg) { res = ((int (*)[arg][b]) foo)[0][0][0]; }
void f1 (void) { f2 (a); }
--------------------------------------------------------------
generates an ICE in make_ssa_name_fn, during remap_type, because
the TYPE_SIZE_UNIT of the outer array contains a freed SSA_NAME.
(Sorry for the empty description, gateway timeout.)
