Summary: part_render crash when speed is set high

Initial Comment:
I have a particle system with part_head with no arguments (defaults to 1000 particles max).
I use part_render and start rendering. 
Then I set part_head's speed to eg. 300, then my pd crash.

My system is: PD 0.42.5 - GEM 0.92.2 - Ubuntu 9.04 64 bit - NVIDIA GTX 260

cool that it works

when downloading svn-snapshot via viewvc, all the executable flags are
stripped away (i guess that's for safety reasons)

sorry for the last comment...

solved the autogen problem with "sh autogen.sh"

I've compiled succesfully the source from
http://pd-gem.svn.sourceforge.net/viewvc/pd-gem/branches/

After the first tests it's seems to be ok!!!

Thanks a lot!!! for the patch and GEM develop!!!

ciao, dario

I'm miss something?

PS: I'm trying to compile the sources downloaded from
http://pd-gem.svn.sourceforge.net/viewvc/pd-gem/branches/
But I'm not able to start the compilation:
when I run ~/pd/source/gem-0.92-2-part_render/src$ ./autogen the console
tell me "Nessun file o directory" (No file or directory)
No problem in the old 0.92-2 source.
Don't know what to do now, sorry

thanks, dario

trunk and branch/0.92

Message:
could you provide a backtrace of the crash?

on linux/osx/similar you can use gdb for producing one:
$ gdb -args /path/to/pd -lib Gem -open /my/faulty/patch.pd
[...]
(gdb) run
[... do something to trigger the crasher bug ...]
(gdb) backtrace
[...]

with -verbose flag the console says "Errore del bus" (italian) -> "Bus
