[PD] rvbap crashes

[Iain Mott]

Hi list,

I'm having problems already cited elsewhere with rvbap - whereby it
crashes with a "Signal 6" when adjusting the azimuth and having first
configured the external with a 2D speaker array (eg. with a message:
"define_loudspeakers 2 -45 45 0 180").

While i've seen this reported i haven't seen any solutions. eg. here:
http://sourceforge.net/tracker/index.php?func=detail&aid=3383881&group_id=55736&atid=478070 

I've tried this with pdextended on linux (i'm using ubuntu 11.04) and
also by compiling the external with this source:
http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/vbap/

Same thing.

Does anyone have any suggestions?

thanks,

Iain
