[PD] Gem/Pd crashing in edit mode in osx

[Nick Fells]

Hi again.

Pd 0.37 from Hans' osx installer, Gem 0.87, osx 10.2.8. After stopping 
rendering, I often get a crash when editing patches:

'GEM: Stop rendering
pd_gui: pd process exited
/Applications/Pd37.command: line 3:   457 Bus error               
/Applications/usr/local/bin/pd -verbose -midiindev 1 -lib 
/Applications/pd/extra/Gem -audiodev 2 -listdev'

This seems to happen with the Gemwin open or closed: actually seems 
happier editing whilst rendering, bizarrely. It does the 'pd_gui' bit 
when I try to move or add objects.
