Reduced testcase:

typedef int GBool;
class GString { };
class XRef;
struct Ref { };
enum ObjType {
    objBool,   objInt,   objReal,   objString,   objName,   objNull,  
objArray,   objDict,   objStream,   objRef,   objCmd,   objError,   objEOF,  
objNone };
class Object {
  public:
    GBool isInt() { }
    GBool isNum() { }
    GBool isArray() { return type == objArray; }
    int getInt() { }
    double getNum() {
  return type == objInt ? (double)intg :
  real;
  }
    int arrayGetLength();
    Object *arrayGet(int i, Object *obj);
    ObjType type;
    union {
      int intg;
      double real;
    };
  };
class Dict {
  public:
    Object *lookup(char *key, Object *obj);
  };
typedef unsigned int CID;
struct GfxFontCIDWidthExcepV {
    CID first;
    CID last;
    double height;
    double vx, vy;
  };
struct GfxFontCIDWidths {
    GfxFontCIDWidthExcepV *     excepsV;
    int nExcepsV;
  };
class GfxFont {
  public:
    GfxFont(char *tagA, Ref idA, GString *nameA);
  };
class GfxCIDFont: public GfxFont {
    GfxCIDFont(XRef *xref, char *tagA, Ref idA, GString *nameA,       Dict
*fontDict);
    GfxFontCIDWidths widths;
  };
GfxCIDFont::GfxCIDFont(XRef *xref, char *tagA, Ref idA, GString *nameA,        
 Dict *fontDict):   GfxFont(tagA, idA, nameA) {
    Dict *desFontDict;
    Object obj1, obj2, obj3, obj4, obj5, obj6;
    int excepsSize, i, j, k, n;
    if (desFontDict->lookup("W2", &obj1)->isArray()) {
      while (i + 1 < obj1.arrayGetLength()) {
        if (obj2.isInt() && obj3.isInt() && i + 4 < obj1.arrayGetLength()) {

      }
    }
}
