Complex Matrix alignement

[unrue]

Dear Intel developers,

i'm trying to do cache alignement over struct array defined as is:

[cpp]struct complex_32 {
    float32 r;
    float32 i;
};
typedef struct complex_32 complex32;
static complex32  **traces;
traces = (complex32 **)malloc( *num_elems * sizeof(complex32 *));
for (i = 0; i < *num_elems; i++) 
    traces = (complex32 *)malloc( *num_samples * sizeof(complex32));[/cpp]

i want to align for 16 bytes. Which is the right syntax using __declspec(align(16))) ?

Actually, using _mm_malloc instead of malloc, the code crashes on forst _mm_load_ps intrinsic.

Thanks in advance for the help.
