Description
The host runs Linux 3.2.6 and Virtualbox 4.1.8. I ran memtest86+ all night. No RAM errors.
Linux guest: Runs Kernel 3.2.6. When compiling the kernel sources, gcc/as/ld randomly segfault.
Windows guests are also affected: Occasionally reboots, shows graphics corruptions
It doesn't seem to matter, how many CPUs I assign to the guests. The segfaults eventually happen. I will attach /proc/cpuinfo, VBox.log, and the kernel config of my host system.

I have lowered the number of CPUS to 1, turned off IO-APIC and tried to reproduce.
When the host is freshly bootet, the error doesn't seem to happen. However, one day of usage and a few suspend to ram cycles, the error starts to appear in a freshly started guest.
To reproduce, I execute
cd /usr/src/linux && while make clean all; do true; done
in the guest and continue working on the Host. The segfault eventually appears.

Do you think that the suspend-to-ram cycles are required to reproduce these errors? What is the type of your host graphics card?
This guy reports the same symptoms as me: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=651012
