It is certainly good advice to optimize for the correct processor, but using unsupported instructions typically result in a SIGILL not a SIGSEGV. It would help to see the actual disassembly around the fault and machine register contents. It smells like alignment problem. -- Csaba/Jester ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
