Same f.c source as exists in the description

#include "float.h"

typedef short v2i16 __attribute__((vector_size(4)));
typedef int v2i32 __attribute__((vector_size(8)));
typedef long long v2i64 __attribute__((vector_size(16)));
typedef short v4i16 __attribute__((vector_size(8)));
typedef int v4i32 __attribute__((vector_size(16)));
typedef char v8i8 __attribute__((vector_size(8)));
typedef short v8i16 __attribute__((vector_size(16)));
typedef char v16i8 __attribute__((vector_size(16)));

void func(TYPE a) {
//crash
a+=1.0f;
a-=1.0f;

//OK
a+=1;
a-=1;
}

//Executing clang -DTYPE=v2i32 f.c
// clang-8:

differing type!"' failed.
