Compiler output:
$ gcc -mno-sse2 testcase.c
testcase.c: In function 'foo':
testcase.c:6:6: internal compiler error: in copy_to_mode_reg, at explow.c:635
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Tested revisions:
r160048 - crash
r153685 - crash
4.4 r158133 - crash

----- testcase.c -----
typedef __attribute__((vector_size(16))) char type;

extern void bar(type);
void foo(type x) { bar(x); }
----------------------


A bit different testcase gives:

$ gcc -mno-sse2 testcase2.c
testcase2.c: In function 'foo':
testcase2.c:4:29: internal compiler error: in emit_move_insn, at expr.c:3428
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

----- testcase2.c -----
typedef __attribute__((vector_size(16))) char type;

extern void bar(type);
void foo(void) { type x; bar(x); }
-----------------------
