Segfault in VBoxDD.so with Windows guest after some time

[Paweł Paprota]

I'm using 32-bit Arch Linux (kernel 2.6.29) with 32-bit Windows XP guest to run a HTTP proxy server inside the VM and proxy Linux Firefox traffic through it.

Starting with VirtualBox 2.2.2 I get a segfault after some time (several minutes, sometimes seconds) of web browsing on the host.

Below is the stack trace obtained by attaching gdb to VirtualBox process.

Program received signal SIGSEGV, Segmentation fault.

Back trace properly formatted:
