It looks like (b) versions are skipped a lot, for instance in dwg_decode(), you have:

```
  PRE (R_13b1)
...
  VERSIONS (R_13b1, R_2000)
...
  VERSION (R_2004)
...
  VERSION (R_2007)
...
  SINCE (R_2010)
...

// This line should not be reached
...
```

meaning R_2000i, R_2002, R_2004a, R2004b, R2004c, R_2007a, R_2007b, R2010b get skipped and that last line gets reached when trying to decode one of those versions.
