编译不过表达式必须含有常量值

[Tinide]

bool b58tobin(void *bin, size_t *binszp, const char *b58, size_t b58sz)
{
size_t binsz = *binszp;
const unsigned char b58u = (void)b58;
unsigned char *binu = bin;
size_t outisz = (binsz + 3) / 4;
uint32_t outi[outisz];
uint64_t t;
uint32_t c;
size_t i, j;
uint8_t bytesleft = binsz % 4;
uint32_t zeromask = bytesleft ? (0xffffffff << (bytesleft * 8)) : 0;
unsigned zerocount = 0;

outi声明要用new 或者malloc吧
