LMMS 1.1.3 crashes often on linux

[Konrad2]

Hello. I'm new to LMMS and to this forum

I'm discovering LMMS but it crahes too often. In the terminal sometimes I get just "segmentation fault", and sometimes I get:

Code: Select all

ASSERT: "asize <= aalloc" in file /usr/include/qt4/QtCore/qvector.h, line 474
Aborted

Is there anything I can do to prevent it from crashing? It's such a great program

Thank you

[musikbear]

Most likely, it is the distro you have your version from
please post your:
* OS (distro aso
* lmms vers
* hardware specification (ram & soundcard is the most imortant)
* lmms sound device chosen

[Konrad2]

I'm using it on both Ubuntu 14.04 and Mint 17.1, both 64-bit. (I get the same message on both distros)
LMMS 1.1.3, as stated in the thread title
My laptop has 6GB ram and I'm using Logitech H390 usb headset, which according to "aplay -l" is card 2, device 0. Therefore I put "hw:2,0" in LMMS audio settings.
Tell me if you need any more info.
Thank you

Konrad2 could you please make a Debug build and offer backtraces for your crashes? There are instructions here:

https://github.com/LMMS/lmms/wiki/Debugging-LMMS
https://github.com/LMMS/lmms/wiki/Compiling-lmms

[Konrad2]

I've never done that before but I'll try.
Thank you

[Konrad2]

Is this what you asked me to do?

This compiled version crashes SO often, I don't even last 30 seconds
In all crashes I opened Skiessi-C64 project tile

I have the same problem. I looking for any solution but I don't know where can I start to it.
I try to did the dbg stuff and I can't did that.
I watched these crashes may be incompatibilities when installing the program.
I have obtained the newest version of lmms ( 1.1.3 ) from KXStudio repositories, using the deb file .
ALSA system does not work so use SDL sounds . But lmms often closes
I have a HP notebook. 64 bits. Linux Mint Rebecca 17.1
Thanks.

P.S: Sorry my poor english.

Konrad2, thanks for the backtraces. I had the same issues on my laptop these days, so I reported a bug upstream. Your crash2 and crash3 seem to be related to this issue: https://github.com/LMMS/lmms/issues/2192

As for crash1, that seems to be a good candidate for a bug report, but we'll need a good way of reproducing it to make one

[Konrad2]

Well, If I do what I did before crash1, the compiled version of LMMS always crashes with no exception on Ubuntu 14.04 64-bit. This is how it happens:

Open LMMS
Click on My projects > Demos and double click Skiessi-C64
Press F7 to bring up the piano editor
Click anything anywhere outside the pianoroll, even outside LMMS, like the taskbar (just noticed)
Boom

This doesn't happen on LMMS installed from Ubuntu software manager
