This boils down to

merulo% cat t.c
int main(void)
{
 int var, *p = &var;
 return (double)(unsigned long)(p);
}
merulo% gcc -O -c t.c
t.c: In function 'main':
t.c:5:1: error: unrecognizable insn:
(insn 5 4 6 3 t.c:3 (set (reg:DF 344)
        (unsigned_float:DF (reg/f:DI 328 sfp))) -1 (nil))
t.c:5:1: internal compiler error: in instantiate_virtual_regs_in_insn, at function.c:1630
