With more than one core I get strange internal compiler errors or sometimes a bluescreen after some minutes of building. With the same configuration but only one core the system works fine for hours. Also the same virtual disk image works fine when running with multiple cores on a Windows XP 32 Bit host. My host configuration: Microsoft Windows Server 2003 R2, Standard x64 Edition Service Pack 2 4x Dual-Core AMD Opteron(tm) Processor 2218, 2.6 GHz, 4 GB RAM Session log file, box configuration and minidump from the guest OS attached." defect closed guest smp VirtualBox 3.1.6 fixed Windows Windows
