VirtualBox 5.0 101573 Crash on RHEL6.4 in libQtCoreVBox.so.4

[blentz]

Host: RHEL 6.4 x86_64 Problem: I upgraded from VirtualBox 4.3 to 5.0. Afterward, I couldn't even so much as start the GUI interface let alone attempt to boot any VMs.

Each attempt to run the VirtualBox management GUI was met with:

[blentz@d-blentz-kno-0 ~]$ VirtualBox Segmentation fault

So it's back to 4.3 I go.

I am left with entries in dmesg. If you want the core, I can re-upgrade, fix my ulimit and see if I can get a core file for you.

VirtualBox[7761]: segfault at 0 ip 00007f4765c193ff sp 00007fff06ff8230 error 4 in libQtCoreVBox.so.4[7f4765b88000+377000] VirtualBox[7774]: segfault at 0 ip 00007ff63e7393ff sp 00007fff273822f0 error 4 in libQtCoreVBox.so.4[7ff63e6a8000+377000]

I searched and I couldn't find anyone else with this problem in either the bug tracker or the forum.

The only thing weird about my machine is that I have 3xATI Radeon HD 6450 Dual-link DVI running 6 monitors. I am using the proprietary ATI drivers in order to get it working.

Otherwise, I've got a fairly vanilla host.

Just FYI, I opened ticket #14315 for the same issue on CentOS 5.11. (CentOS is a clone of RHEL.) My /var/log/messages file did not contain anything after the "error 4" part of the segfault.

I note yours includes "in libQtCoreVBox.so.4" in the segfault output. In my ticket, I noted that I do not meet the required minimal QT version per the user guide. (<https://www.virtualbox.org/manual/ch02.html#install-linux-host>). Since you're on RHEL 6.4, then you are probably using qt-4.6.2... so you don't meet the minimum of 4.8, either.

Maybe I was wrong in my ticket to state that this probably isn't the cause of my problem. Could it be the cause of yours, too?

[Frank Mehnert]

Ticket #14315 is most likely different because this ticket shows segfaults in libQtCoreVBox.

[Frank Mehnert]

Any improvement with VBox 5.0.2?

Replying to frank:

It seems no, I'm getting segfault with this trace:

#0  0xb4e8ee75 in ?? () from /opt/VirtualBox/libQtCoreVBox.so.4

(not on RHEL)

Is there any update on this issue? I have implemented a virtual device (.so) based on 5.0.6, but I need to run on RHEL. If not fix for this is found, I will need to port it back to an older version of VBox which I really hope to avoid.

[Frank Mehnert]

No update. If you can provide a core dump I would have another look.

[Frank Mehnert]

Another user reported that upgrading the host fixes the issues for him, see #12923. Would that work for you as well.

[RicV]

I still have never been able to run the VirtualBox 5.0.x GUI on Red Hat 6.5, though 4.3.32 does work. I have so far avoided it by just using Ubuntu, but I really need to migrate to a Red Hat machine now, so this is becoming a serious problem for me.

bash-4.1$ VirtualBox
Segmentation fault
bash-4.1$ VBoxManage -v
5.0.20r106931

Here is what I get from dmesg:

VirtualBox[118165]: segfault at 0 ip 00007ff22aa6d3ff sp 00007fffc35eed00 error 4 in libQtCoreVBox.so.4[7ff22a9dc000+377000]

What can I do to help sort this out?

Please reopen if still relevant with VBox 5.1.22 (which uses Qt5).
