The short program below

#include <stdio.h>
typedef int m128 __attribute__ ((mode(V4SI)));

typedef union {m128 ti; unsigned int si[4];} m128x;

int main(void)
{
    m128x a;
    m128 w;
    a.si[2] = 1;
    w = a.ti;
}

gives an ICE in expr.c line 2748 -- this is the abort() command when the two sides of an emit_move_insn have incompatible modes.
