Segfault without messages
by Brian Neltner 25 Oct '10

25 Oct '10

Dear PureData developer list, I have recently switched from Max/MSP to PureData as I like the fact that it runs on linux and also like that it is open source. I am using it for a big project in order to analyze audio using the aubio plugin, and then based on the analysis output open sound control packets using packOSC and sendUDP to a locally running server which will control a large number of LED lights. The program I am using to analyze the music and output control signals is pretty basic, but for some reason after running for an hour or two, PureData inexplicibly segfaults without any debug messages even at pdextended -d 10. I assume at that point any debug messages that are being generated are being printed, so something is happening for which there is no debugging handler to explain the problem. I have attached the offending script. It is running on ubuntu 10.04 using the PD repository for lucid, and is using the pd-aubio library from that distribution, with the external copied from /usr/lib/pd/extras/ to /usr/lib/pd-extended/extras/ Literally the output from running in the terminal before crashing is: pd ping; pd ping; ... (repeated) pd gui; pd process exited Segmentation Fault Not very useful... Thanks for any help... I was planning to try to use pd to control the lighting at a pretty big show next week, so this really is throwing a wrench into my plans. It would definitely be a major pain to have to reimplement this in C or something =/ Sincerely, Brian Neltner

Category: puredata Group: v0.43 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Hans-Christoph Steiner (eighthave) Assigned to: Miller Puckette (millerpuckette) Summary: interrupting tabwrite~ prevents array redraw Initial Comment: When writing data to an array by banging a [tabwrite~], if a bang is sent to [tabwrite~] before it fills the array completely, the array never gets redrawn. If a [stop( message is sent, then it does get redrawn. The attached patch from Luca Princic illustrates this problem. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=3093068&group_…

some late 0.43 patches...
by IOhannes m zmoelnig 18 Oct '10

18 Oct '10

hi miller, list... i hear you are busy doing some bugfixing for the 0.43 release with hans... working on the integra-live project i noticed a number of problems with the portaudio support in Pd, some of them being real showstoppers (read: they crash Pd) i submitted a number of patches to sourceforge that should fix these problems (as well as one last amendment to the functions exported in s_stuff.h, needed for my external controlling the audio settings) it would be great if you could include them. fgmasdr IOhannes
