line break error in tied chords

[VSD]

The following example gives the following error several times in the log:

programming error: infinity or NaN encountered while converting Real number
continuing, cross fingers
programming error: setting to zero
continuing, cross fingers


if there's no \break then there's no error. Note that there's a collision  
with the articulation too, probably as a side effect of the error.

I think this error has been reported recently. Here's a ly example.


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\version "2.7.6"

\relative c'
{
        R1 * 4
        
        r2 r4 r16 <b' e a>8^> <b e a>16^> ~
        \break
        <b e a>4 r4 r2
}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% EOF

thanks and greetings,
