Bug Report OBS crashing after 2 minutes

[Laszlo Fogas]

I have a screen recording setup. Screen + webcam + microphone, YV12(emulated) software x264 encoder

OBS recording nicely but crashing after a minute and a half. I'm able to reproduce consistently, the crashes happen after 90 seconds, and never survived 4 minutes.

In "journalctl -xe" i see the following error:

*** longjmp causes uninitialized stack frame ***: obs terminated


Anyone seen this?

Thanks.

I had the same problem as you had and successfully resolved it. OBS kept crashing after several minutes. This is actually due to a bug in curl[1], which is a dependency of OBS. The solution was to recompile curl to use c-ares[2] and to reinstall OBS. The post in [1] offers an explanation.

Here is an excerpt from the backtrace when OBS crashes.[3]
