Subject: [Bug libstdc++/37958] num_get<>::do_get(bool) sets eofbit flag incorrectly when boolalpha == true
Date: Sat, 01 Nov 2008 15:53:00 -0000	[thread overview]
Message-ID: <20081101155232.8036.qmail@sourceware.org> (raw)
In-Reply-To: <bug-37958-16694@http.gcc.gnu.org/bugzilla/>



------- Comment #11 from tsyvarev at ispras dot ru  2008-11-01 15:52 -------
It is not nitpicking. Case with empty sequences is only demonstration, that
code behaviour is not confirm to the standard.

Really, it seems that in every succesfull matching it will be unnecessary
comparision (in == end). For example, for target sequences "false" and "true"
and input sequence "false" eofbit flag won't be set in err, but when __beg
points to 'e', (++__beg == __end) in the last if-operator inside for-cycle will
return true.
