 |
|
Hello,
I have been using nextcloud-client in the past to sync files to my nextcloud instance.
Today I noticed that its tray icon was missing, so I tried to start it manually. Still not working.
When I start it from the command line, it shows a segfault directly after start, and in dmesg it prints the following:
| Code: | [ 9803.413903] nextcloud[30903]: segfault at 8 ip 00007f4ebccae594 sp 00007ffde9425a98 error 4 in libQt5Core.so.5.15.14[7f4ebca77000+2de000] likely on CPU 8 (core 0, socket 0)
[ 9803.413917] Code: 01 01 f6 0f b6 51 20 89 d0 83 e2 fd d0 e8 09 f2 83 e0 01 88 51 20 c3 90 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 00 f3 0f 1e fa <48> 8b 47 08 48 8b 40 38 48 8b 40 38 c3 66 66 2e 0f 1f 84 00 00 00 |
I already tried to rebuild nextcloud-client and also qtcore, but it still does not change this behaviour.
The system has been fully updated today, and revdep-rebuild also shows no problems.
Any other ideas that I could follow up to fix this?

In my opinion, it is premature to mark this thread as solved.
First, there is no explanation for why LTO does not work. LTO should work, though it may require fixes upstream to reach that point. I see nothing in the linked Github issue that diagnoses the root cause or attempts to fix the crash.
Second, until LTO does work, it would be nice to have the ebuild disable LTO so that users cannot build a known-broken configuration. I see no reference here to a Gentoo bug report for this. However, on searching, I found net-misc/nextcloud-client-3.12.3: segmentation fault when LTO is enabled, which may or may not be the same problem. This thread does not specify the faulting version, nor provide a backtrace to confirm that it is the same fault. |
