Description David Binderman 2005-06-30 05:48:19 EDT
Description of problem:

I just tried to compile package festival-1.95-3 from Redhat
Fedora Core development tree with the gcc 4.0.0 compiler and
the compiler flag -Wall.

The compiler said

rateconv.cc:387: warning: operation on 'outidx' may be undefined

The source code is

            fir_stereo(inp + inoffset + inbaseidx,
                       coep + cycctr * firlen, firlen,
                       outp + outidx++, outp + outidx++);

I agree with the compiler - this is undefined code. Suggest avoid
incrementing variable "outidx" twice between sequence points.

Better code might be

            fir_stereo(inp + inoffset + inbaseidx,
                       coep + cycctr * firlen, firlen,
                       outp + outidx, outp + outidx + 1);
            outidx += 2;

Can you create a patch, attach it here and send it upstream?  Thanks.
Comment 2 David Binderman 2005-07-01 04:17:53 EDT
>Can you create a patch

I could, but I have no way to test the patch in the festival package.

Suggest forward bug report to upstream.
Comment 3 Matthew Miller 2007-03-13 17:00:29 EDT
I'm working on an updated package which includes this fix. Still should be sent
upstream.
Comment 4 Matthew Miller 2007-03-13 17:20:27 EDT
See bug #232105 for in-progress updated packages which address this issue.

Comment 6 Matthew Miller 2007-03-20 15:02:02 EDT
This issue should be resolved by the release of festival-1.96-0.11, now in the
development tree. (See bug #232105 for details.)

Please reopen if there's still a problem. Thanks.
