Package: virtualbox
Version: 5.2.6-dfsg-3+b1
Severity: normal
Dear Maintainer,
When running a Windows 7 guest using the PulseAudio host audio driver
and either "ICH AC97" or "Intel HD Audio" audio controller, running
PowerShell and causing repeated beeping (e.g. by invoking ^G repeatedly)
will cause VirtualBox to crash with SIGSEGV. I was able to reproduce
the issue using the Microsoft-provided "IE8 on Win7 (x86)" VM image[1]
but was unable to reproduce it from terminal beeps using a Linux image.
The backtrace from the core dump is as follows:
Program terminated with signal SIGSEGV, Segmentation fault.

I could host the entire core dump if it would be useful. The host
system has pulseaudio 11.1-4 installed.
Let me know if I should report the issue upstream. I couldn't find a
way to run the distro-agnostic binary package without installing it,
which I'm hesitant to do. So I have filed the issue here to start.
Thanks,
Kevin
