with new option parser requires to run with.

./frysk/bindir/ftrace -- gnome-terminal --disable-factory

happens in LinuxIa32Syscall.syscallByNum at this point:

else
{
return ipcSubcallList[subSyscallNumber];
}

ipcSubcallList has 24 elements, so the 24 is looking for the 25th element.

That 24 is provided by:
subSyscallNumber = (int) task.getIsa().getRegisterByName("ebx").get (task);
