I am working on my first project in Max 8 using the MC Wrapper. Occasionally 

I experience crashes of Max 8, when I am opening a nested [bpatcher] (loaded as abstraction) that make use of MC audio

. I am not able to reproduce this reliably, hence it's too early for a bug report.

That it is related to MC signal is a (educated ;) ) guess.

Anyone experiencing the same? Maybe we can narrow it down.

when this happens you should probably save the crash log. that would probably be helpful

Crash Report.txt

Here it is. I only post the stack of the crashed thread here (not to mess up the forum). T

he full report is inside the attached file.

The crash report seems to indicate that there are grouped object inside the bpatcher or the bpatcher is part of an object group. But this is not the case.

One more information. During the working process I did group some objects and ungroup them later. But the crash happens also when opening/saving [bpatchers] that do not contain formerly grouped objects. Anyone experiencing the same?

The crash is definitely in grouping code; if you can figure out a way to reproduce, send it along to support, please.

My max 8 is crashing too when copying and pasting the curve on functions.

Im on windows 10, last update (i think), envy hp 15 j106la.

Hi Jemery.
My max 8 is crashing too when copying and pasting the curve on functions.
Im on windows 10, last update (i think), envy hp 15 j106la. 

@Jeremy: I found that there still were some grouped objects inside (nested) 

. After ungrouping them - so far - it didn't crash anymore. I hope that later this week i'll have time to do some more systematic investigation and report back to support.

Thanks @JAN, please send it along once you've isolated it.

@STGO DDV please don't hijack threads -- if you have found a reproducible crash, the best thing to do is contact support (or start your own thread here in the forum). I cannot reproduce this crash on an OSX system, FWIW, although I can reproduce a crash on close after following your steps. I can investigate, thank you.

Ok Jeremy. As the title of the forum is vagely "Help to identify bugs" i thought it was precisely that, namely help to identify any type of bug crashes. I'll send that bug to support! Thank you for trying to reproduce.

@STGO DDV, I found a bug in the function copy/paste code and it's already fixed, but yes, please drop a note to support so they can track it as well. You can reference ticket #12498. Thanks, Jeremy

That's great. I've already sended a message to support. Thanks 4 ur help.

Renamed the thread to be less generic. Thanks!

I just experienced the same. I had a bpatcher that I have used for more than a year and it started crashing as soon as I left a some groups active. I got rid of them and voi-lá, everything is working now.

Max 8 groups crash in bpatcher
