--- Comment #6 from Vittorio Zecca <zeccav at gmail dot com> ---
The following is a shorter version of Marc's test case:

unsigned __edx;
__cpuid (0, 0, 0, 0, __edx);
}
int __get_cpuid (unsigned int __level, unsigned int *__eax, unsigned int
*__ebx, unsigned int *__ecx, unsigned int *__edx) {
fail: return 0;
}
typedef int IV __attribute__((vector_size(16)));
typedef union {
int s;
IV v;
} U;
static U i[2], b, c;
void check0(void) {
b.v = __builtin_shuffle (i[0].v, i[1].v, (IV){ 4, 0, 0, 0});

As an aside, in gcc 4.8.1 source code, before line 6995 of gcc/expr.c I put
printf("\nexpr.c:6995 value->code=%d NUM_RTX_CODE=%d\n",(int)
value->code,NUM_RTX_CODE);
gcc_assert((int) value->code < NUM_RTX_CODE);
and I get an ICE there because value->code is 34816 and NUM_RTX_CODE is 145
Indeed at line 6995 ARITHMETIC_P (value) accesses rtx_class[(int) value->code]
but the array rtx_class has only NUM_RTX_CODE elements.
However, I do not know how this is relevant to this issue.
