-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Jiawei Wang, I suppose the programmer assumed that line 694 is reached at least once during the loop, despite the if-clause around it. But even if this were not the case, many C++ compilers will initialise f2 to zero when it is declared although I don't think the standard guarantees this.
