Recompiled it on an up to date 64 bit fedora 15 machine. Thats much easier, but unfortunately just the same error message when I run it. Disabling SELINUX makes no difference btw.
Additional info: /var/log/messages also contains: kernel: [17259.970316] linux[14027] general protection ip:602a2e7f sp:7fffe11a09e8 error:0 in linux[60000000+4aa000] Here are the last few lines from a strace: write(2, "Checking syscall emulation patch"..., 46Checking syscall emulation patch for ptrace...) = 46 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x60605b50) = 14049 --- {si_signo=SIGCHLD, si_code=CLD_TRAPPED, si_pid=14049, si_status=SIGSTOP, si_utime=0, si_stime=0} (Child exited) --- wait4(14049, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGSTOP}], WSTOPPED, NULL) = 14049 ptrace(0x1f /* PTRACE_??? */, 14049, 0, 0) = 0 --- {si_signo=SIGCHLD, si_code=CLD_TRAPPED, si_pid=14049, si_status=SIGSEGV, si_utime=0, si_stime=0} (Child exited) --- wait4(14049, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGSEGV}], WSTOPPED, NULL) = 14049 write(2, "check_sysemu : expected SIGTRAP,"..., 51check_sysemu : expected SIGTRAP, got status = 2943 ) = 51 exit_group(1) = ?
