Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: rendering (e.g. display) Group: linux
Status: Open
Resolution: Fixed Priority: 5 Private: No Submitted By: zomoipotoi (zomoipotoi) Assigned to: Nobody/Anonymous (nobody) 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

Message: I've substituted the two files (part_render.cpp and part_render.h) in my gem 0.92.2 folder. Then make give me the following error:

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

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 [...]

Message: with -verbose flag the console says "Errore del bus" (italian) -> "Bus error" (I think this is the translation) when the crash occur
