strict aliasing violation?

hi, i'm reading through the simd version and this to gain some familiarity as to what's going on and what techniques are being used. does this line not violate strict aliasing?

uint64_t * pw64 = *(uint64_t **) pw;

Decoded size doesnt match encoded size.

Hey Guys,

A small code used to show the problem i m facing using streamvbytes library on linux

#include <stdint.h>
#include <streamvbyte.h>
#include <malloc.h>
#include <stdio.h>

int main( void )
{
size_t encoded = 0, decoded = 0;
uint8_t *set = malloc( 1024 );
uint32_t entry[ 2 ];

entry[ 0 ] = 10;
entry[ 1 ] = 0;

encoded += streamvbyte_encode( entry, 2, set );
for( size_t i = 0; i < 2; i++ ) {
decoded += streamvbyte_decode( set + decoded, entry, 1 );
}
printf( "encoded size : %zd vs decoded size : %zd\n", encoded, decoded );
free( set );

return 0;
}

When I run this code I got this output 👍

encoded size : 3 vs decoded size : 4

Can you help me finding the issue ?
