Recordmydesktop Crashing With Segmentation Fault

[Mukesh Kumar]

Hi Team,

While trying to explore features/bugs in recordmydesktop application, I have come across a situation where the Application is crashing and showing the message "Segmentation Fault". I tried to debug the issue, but for some reason couldn't figure it out. The crash is very simple to reproduce. Please find below all the information:

recordmydesktop version: recordMyDesktop v0.4.0
OS used: Kali linux 2020.3 Vbox

Steps to repro:

1. Start the recording using default command with default options "recordmyscreen"
2. Once, the recording is started and it shows "Capturing", press "CTRL+ C" twice pretty fast.
3. Once, the 2nd CTRL+C is pressed, it will show the error "Please wait...
Output file: out-16.ogv
[5%] ^CSegmentation fault
"
4. Also, there won't be any recording saved as well.

I have pasted the entire transaction below and attached a screenshot as well:

kali@kali:~$ recordmydesktop
Initial recording window is set to:
X:0 Y:0 Width:1920 Height:940
Adjusted recording window is set to:
X:0 Y:6 Width:1920 Height:928
Your window manager appears to be Xfwm4

Detected compositing window manager.
Reverting to full screen capture at every frame.
To disable this check run with --no-wm-check
(though that is not advised, since it will probably produce faulty results).

Initializing...
Buffer size adjusted to 4096 from 4096 frames.
Opened PCM device default
Recording on device default is set to:

For getting the debug log, I installed the recordmydesktop on a new installation of Ubuntu and reproduced the issues

NOt sure if the debug file got uploaded successfully or not, hence uploading it manually

Hi Team,

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
