target app, basically... not clear what's going wrong, but it could be a
syscall that's not working properly.
The easiest way to see what's going on is to turn on tracing. The Exec flag
(might still be called InstExec in your version) traces instruction execution,
and the Syscall and SyscallVerbose flags trace syscall emulation. The complete
list of traceflags is in src/base/traceflags.py. I'd suggest adding this to
your command line after m5.debug but before your .py file:
--trace-flags=Exec,Syscall,SyscallVerbose --trace-start=5278460000
and then redirect the output to a file, then look through it and see if you can
figure out where the null pointer is coming from.
