Hi,

I have attempted to play the following .csd file (in version 5.07) and  
after a couple of seconds it always segfaults on me. The same buffer  
and MIDI settings are fine on other instruments I have designed, but  
for some reason, this soundfont instrument gives me trouble.

here is a link to the .csd file:
http://www.akjmusic.com/horn.csd

here is the soundfont used in the instrument itself:
http://www.akjmusic.com/horn.sf2

You will have to change the filepath in the .csd to where you are  
putting the font on your system if you want to recreate this bug.

This is the console message:
