minicom 2.4 执行runscript时提示“bigger 50 bigger100”

此问题为minicom的一个bug，可以参考:

[minicom-Bugs][313217] runscript crash when using environment variable in scripthttp://lists.alioth.debian.org/pipermail/minicom-devel/2011/001101.html

2.4 对应的源代码:

char *getword(char **s)
{
  static unsigned bufsize;
  static char *buf; /* The buffer is only growing and never freed... */
  unsigned int len;
  int f;
  int idx = 0;
  const char *t = *s;
  int sawesc = 0;
  int sawq = 0;
  const char *env;
  char envbuf[32];

  if (**s == 0)
    return NULL;

  for (len = 0; ; len++) {
    if (idx + 3 > (int)bufsize)
      {
        bufsize += 50;
        fprintf(stderr, "bigger %d\n", bufsize);
        buf = realloc(buf, bufsize);
      }

bufsize 未初始化

minicom 2.5 已经修正:

char *getword(char **s)
{
  unsigned int len;
  int f;
  int idx = 0;
  const char *t = *s;
  int sawesc = 0;
  int sawq = 0;
  const char *env;
  char envbuf[32];

  if (**s == 0)
    return NULL;

  for (len = 0; ; len++) {
    if (sawesc && t[len]) {
      sawesc = 0;
      if (t[len] <= '7' && t[len] >= '0') {
        buf_wr(idx, 0);
        for (f = 0; f < 4 && len < bufsize() && t[len] <= '7' &&
             t[len] >= '0'; f++)
          buf_wr(idx, 8 * buf_rd(idx) + t[len++] - '0');
        if (buf_rd(idx) == 0)
          buf_wr(idx, '@');
        idx++;
        len--;
        continue;
      }
