Comment 2 for bug 2042743

I have the same issue.
Running "raw" (not snap) vlc under Ubuntu 22.04
vlc/jammy-apps-security,now 3.0.16-1ubuntu0.1~esm1 amd64 [installed]

$ vlc
VLC media player 3.0.16 Vetinari (revision 3.0.13-8-g41878ff4f2)

Aborted (core dumped)

Note #1: disabling hardware acceleration works around the issue.
`vlc --avcodec-hw=none` does not abort when seeking.

Note #2: I was not able to get a proper call stack because libavcodec.so.58 symbols are not available.
