makemkvcon segfault
Posted: Tue Feb 27, 2024 2:19 pm
Setup:
Hardware M1 Mac Mini
OS: Fedora Asahi 39 (6.6.3-413.asahi.fc39.aarch64+16k)
makemkv version: 1.17.6 (not tried on earlier versions)
Repro:
build & install makemkv 1.17.6 according to instructions, then run makemkvcon info
Output:
Additional details:
I enabled debug logging in makemkv and noticed that the seg fault happens in makemkvcon during the call to MainWnd::MainWnd : App->UpdateAvailableDrives(0);
In the log it's the last Transact (so far) of apCallUpdateAvailableDrives:
I have no idea where the issue lies but am happy to dig deeper. Could be related to pagesize since Asahi Linux uses 16K pages.
This setup is considered exotic at the moment so it probably doesn't affect many people. I'm in the process of making it my daily driver but have a backup machines for makemkv for now (runs great on Fedora 39 / amd64
)
