Re: [PD] dyn~ crash

[Thomas Grill]

Hi Marius,






all the best,
Thomas

it's a problem inherent in PD, which was discussed just a few days ago. An object can't be deleted when messages sent by it are still processed. It's easy to circumvent in your case: Delay the closing just a bit.... find the attached patch. I don't think this is something that dyn~ should "fix". By the way - with your patch attachment you exposed something that might be considered a pd bug: Two patches that are pasted into one file will open to canvases, but pd will crash on every save attempt of it.

it is easy to build a loop which can crash dyn~, and I wonder if it would be possible to avoid a crash. I use objects, which play for a random anount of time and then they send their id when they're finished and so dyn knows that it is time to delete them. I understand wyy this is a problem, and I also found some sort of work around. but it would be easier if dyn would catch that recursion. #X obj 223 194 cnv 15 100 60 empty empty empty 20 12 0 14 -258049 -66577 UNSUBSCRIBE and account-management -> http://lists.puredata.info/ listinfo/pd-list
