What does /proc/cpuinfo say? Because the culprit is known to be an illegal instruction, then run under a debugger such as gdb, and find out exactly what instruction that is. $ gdb valgrind (gdb) run <<SIGSEGV>> (gdb) bt (gdb) x/x $pc (gdb) x/i $pc (gdb) x/8i $pc-4*4 (gdb) info reg (gdb) x/16x $sp -- ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
