Bug #: 57167 Summary: [graphite] Virtualbox 4.2.2 and above wont work with multiple CPUs. Classification: Unclassified Product: gcc Version: 4.7.2 URL: https://bugs.gentoo.org/show_bug.cgi?id=432412 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: de.tec...@gmail.com Virtualbox when compiled with Graphite with the following compiler options -- -march=native -O2 -fomit-frame-pointer -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity Fails to run the virtual machine when it's having multiple CPUs. i.e. it only works when CPU is set to 1 in number. If I've set it to multiple, the kernel hangs.
