Reduced test-case:

cat pr107044.C
class Token;
struct {
  void addElement(Token *);
} * fTokens;
class RangeToken;
struct Token {
  virtual void addRange();
  virtual void mergeRanges(const Token *);
};
inline void Token::mergeRanges(const Token *) {}
RangeToken *createRange(bool =3D false);
struct RangeToken : Token {
  RangeToken();
  void mergeRanges(const Token *);
};
RangeToken *createRange(bool isNegRange) {
  RangeToken *tmpTok =3D isNegRange ? new RangeToken : new RangeToken;
  fTokens->addElement(tmpTok);
  return tmpTok;
}
Token getGraphemePattern() {
  Token *base_char =3D createRange();
  base_char->mergeRanges(0);
}=
