Here is the reduced testcase:
void BZ2_decompress ( int bsLive, int bsBuff, int state, int nGroups)
{
  
  unsigned char uc;
  int t;
  switch (state)
  {
    case 30:
      nGroups = bsLive;
      while (1)
      {
	if (uc == 0)
	  break;
	case 35:;
	  uc = bsLive;
      }
    for (t = 0; t < nGroups; t++);
  }
}
