Could you please try again with 2.4.2~dfsg0-3? If the issue still
exists, please provide log from valgrind? Maybe this could help us
pinpoint the location of the memory leak and the crash.

Bug#948364: audacity leaks memory and crashes

2020-03-21 Thread Antoine Amarilli 
Hi,

Other important points that I just found:

- The leak only occurs under Wayland (I'm using sway and XWayland), not
  with Xorg (tested with i3)

- The leak only occurs when the Audacity window is visible. If it is not
  onscreen, the memory usage doesn't seem to grow.

(I reiterate that the problem doesn't occur when compiling Audacity
myself from source, so it's not a general issue of Audacity not working
under Wayland -- the problem must be with the specific versions of
libraries that I used, or with the packaging, compilation options,
etc.)

Besides, looking at audacity's memory with pmap, what changes when
memory gets allocated is that lines of the following form get added:

> 7f806403864037403740 rw-s- /memfd:gdk-wayland (deleted)

Best,

Bug#948364: audacity leaks memory and crashes

2020-03-21 Thread Antoine Amarilli 
Hi,

I am still having this bug as of today, which makes Audacity unusable. I
compiled Audacity 2.3.3 from source and it doesn't seem to have the same
problem.

So the problem may be in the Debian packaging, or in the use of
different library versions than what I did.

Here is some information about my build:

Bug#948364: audacity leaks memory and crashes

2020-01-07 Thread Antoine Amarilli 
Package: audacity
Version: 2.3.3-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

On my system, audacity seems to be leaking memory during playback. To reproduce,
record anything, then play it repeatedly, or in a loop (Maj+play). The memory
usage of audacity in top grows steadily (around 16 MB/s) until audacity gets OOM
killed or crashes the system.
