Now I don't understand why malloc isn't working
typedef union
{
int64_t int_d;
double number_d;
} Token_data;
typedef struct
{
Token_type type;
Token_data data;
} Token_t;
Token_t *my_token = (Token*) malloc(sizeof(Token_t))
@matrix apart from you casting to Token instead of Token_t, that looks fine.
