All that is needed to trigger this segfault is to select choose a
virtual cd in the devices menu.<br>
<br>
This happens on two separate (Debian based) systems the laptop was
built using deb build and the main PC as a run file install. <br>

If I locate it I will send along the cause.<br>

It happens the second I click on select CD in the device menu.
I must admit that I am not the sharpest knife in the drawer with core
dumps. The dump is 7MB tar'ed (217.5MB) each.
I can send it to you if you like.

<pre wrap="">The core won't help me much since you're running your own builds, and I
wouldn't have the matching debug info.
Did you install the ...-dbg package? Then you should get much more out
of gdb than just some hex values.

<pre wrap="">How about enabling core dumps and looking where it crashes? I tried a
few CD unmount/mount combinations, and couldn't trigger any problems,
neither in VBoxSVC nor in the GUI.
