Frequent Guru Meditation (VERR_IPE_NOT_REACHED_DEFAULT_CASE) since 4.3.12 update

[Trevor Hemsley]

Since updating from VirtualBox-4.2-4.2.18_88780_el6-1.x86_64 to VirtualBox-4.3-4.3.12_93733_el6-1.x86_64 I have been experiencing frequent Guru Meditation -234 (VERR_IPE_NOT_REACHED_DEFAULT_CASE) while running my OS/2 guest.

In almost every case what I have been doing is using a mozilla web browser to look at https web pages. The last 3 were repeatable within the space of about 10 minutes where I fired up mozilla, went to ​https://www.google.com and typed in "brighttalk" in the search box. Since the crash seems to delete my google preferences as well as my my most recent mozilla session, the google page I was on was using their fast search so attempted to present me with the list of hits as soon as I had finished typing "brighttalk" (without the quotes). This was all that it took to recreate the problem for me!

I've also seen the same crash on my bank's internet banking page while transferring money around. Again, https in use.

The host system is an Intel DH67CF mini-ITX board with 8GB RAM, a core i3 3220T processor running CentOS 6.5, fully up to date.

We think we found and fixed the problem. Please could you confirm that this test build fixes the problem for you? Thank you!

[Trevor Hemsley]

Thank you for also fixing my typo in the Summary ;-)

I've downloaded and installed this build and I was unable to recreate the problem in about 15 minutes of browsing around various https web sites so it looks good from here.

Don't suppose there's an extension pack for this test build is there?

The fix was part of VBox 4.3.16 so I guess it's finally fixed. And Extension Packs for the releases are available as well :)
