FreeTSD: failed to destroy key when starting a Windows VM

[ckujau]

When starting a Windows (XP, NT4) VM via VBoxHeadless, the following error appears on the console:

$ VBoxHeadless -s winxp
FreeTSD: failed to destroy key: Undefined error: 0
VBoxHeadless(27472,0xb058b000) malloc: *** error for object 0x11ce50: double free
*** set a breakpoint in malloc_error_break to debug

The VM gets started normally however and is running just fine. So, despite the "error" it's just a warning. I've seen this for a while now and a quick search ​reveals that this warning has been there in 3.2.6 too. I don't know about earlier releases though.

My host system (and the system in the blogentry above) is MacOS 10.6.4. I'm running in 32bit mode now, don't know if this happens for other host types too.

Please reopen if still relevant with VBox 4.0.4.

Yes, it still happens with VBox 4.0.4 (now with MacOS 10.6.6). Again, it does not have any impact AFAICT. I just noticed it's also happening for a Ubuntu Linux VM. I've only seen this for Windows VMs before:

$ VBoxHeadless -s ubuntu

I am having this same error, but unlike the OP, the virtual machine does not start.

$ VBoxHeadless -s Ubuntu

FreeTSD: failed to destroy key: Undefined error: 0

It would be nice to be able to start the VM from the command line. Is there a work-around?

Exactly the same here:

The "FreeTSD: failed to destroy key" message is (and always was) completely harmless. So this bug is just a random collection of crashes which probably have very little in common, and there are no details what could be the root cause.

Just a crash in malloc on OSX...

Please reopen if still relevant with a recent VirtualBox release.
