VBoxSVC segfaults when restoring snapshot

[Chris]

I have an OSX VM with many snapshots. At some point, after using it for a week, I started being unable to restore back to other snapshots. Nothing happens when I try it through the UI. dmesg spouts:

[ 2707.873773] RestoreSnap[7054]: segfault at 88 ip 000000000050de25 sp 00007f27aa4ccb80 error 4 in VBoxSVC[400000+27d000]

I'm still able to create new snapshots, just cannot restore them. The VM boots still. I've attached the gdb output, but it's not that useful because obviously there are no symbols. Other VMs still work fine, it's just this one OSX VM.

Can you provide a core dump?

I have a similar problem: Using VirtualBox 4.2.18 running on Windows 7 64bit, VBoxSVC crashes when I try to restore virtual machine to a specific snapshot. The debugger (VS2010) attached to the VBoxSVC-process prints:

First-chance exception at 0x000007fefcdfbccd in VBoxSVC.exe: Microsoft C++ exception: long at memory location 0x02a1e128..
First-chance exception at 0x000007fefcdfbccd in VBoxSVC.exe: Microsoft C++ exception: long at memory location 0x047fe2cc..

Unhandled exception at 0x000000013ffa892a in VBoxSVC.exe: 0xC0000005: Access violation reading location 0x00000000000000c8.

I DO have a minidump with Heap here but due to data privacy concerns, I cannot upload it here to the open public. Is there any mail address I can send the dump to confidentially?

call stacks of the mentioned crash on win7 host

Problem persists in version 4.3.0. I can revert to a new snapshot but not to a specific one or any snapshot older than it. I'll attach a minidump (created with VS 2010) here.

Problem persists with VirtualBox 5.0 Beta 2

Please reopen if still relevant with VBox 5.1.22.
