Hi,
update: I'm actually seeing spurious crashes in different frei0r
modules, but always in xxx::update(). So I suspect that somehow there is
some versioning problem with vtables & co. I'm always cleaning all old
output files, then run a clean configure and later install; first MLT,
next Kdenlive. But somehow I seem to have messed up something. Any ideas?
For cross-checking, I've now installed a side-by-side Kdenlive from
Kdenlive's testing repository. That one from the Kdenlive ppa's works
without crashing, using the corresponding MLT and frei0r packages. So I
suspect that I may be doing something wrong here, but what?
To add further to my woes: rendering with my self-compiled MLT
immediately fails when started from within Kdenlive. When run
separately, MLT crashes at some later point in time.
Best regards,
Harald

Hi,
I've just upgraded my MLT to the most recent git master, which is
around 10 days old. Now Kdenlive crashes repeatedly after a few
positioning actions in the timeline, always in frei0r-1/multiply.so.
As I'm not sure if MLT is at stake, or some other unnoticed updated
sneaked in, I'm asking here for help first before pointing fingers.
System is Kubuntu 16.04 LTS with backports ppa enable, all updates
installed as of today.
fei0r-plugins is 1.5+git201604011602-0xenial1; maintainer is Vincent ;)
MLT is compiled from git master as of today.
Kdenlive is compiled from git Applications/16.08 as of today.
Render threads is set to 1.
This is the backtrace, any ideas...? Best regards, Harald
