Summary: bang to switch~ while dsp off: Pd exits

Initial Comment:
When a bang is sent to the switch~ object while dsp is turned off (after having been on at least once since start up of Pd), Pd will exit with segmentation fault. This was tested with Pd extended 0.41.4 on OSX 10.5 and on Linux Ubuntu. I guess the bug could be fixed by extending the conditional check in the bang method for block~/switch~: 

if(x->x_switched && !x->x_switchon && canvas_dspstate)

Message:
Above-mentioned bug exists in Pd 0.42-4 as well. I have checked that the
problem is indeed solved with the following (where d_ugen_old.c is the
original file and d_ugen.c the modified version):

diff d_ugen_old.c d_ugen.c
222c222
<     if (x->x_switched && !x->x_switchon)	
---
>     if (x->x_switched && !x->x_switchon && canvas_dspstate)

Hope this bug will be fixed soon cause I want to share a patch including
the switch~ object.

Katja
