The message is saying that the simulated program tried to do an
unaligned memory access which Alpha doesn't support. My first suspicion
is the Alpha ISA implementation which has been changed around relatively
recently, or in some new functions I added to support oddly
sized/aligned memory accesses.
What command line are you using? Have you made any modifications to M5?
If so, please see if you can reproduce this problem with an unmodified
copy. That would make reproducing the problem easier, and let us know if
it's your code or ours.

Hi, all, when I run spec2006 under *Alpha SE* mode, I always got
the following error:
/**** REAL SIMULATION ****

For more information see: http://www.m5sim.org/panic/6e85c706/
I have tried several programs, including perlbench, gcc, bwaves,
all of them went into this error and the outputs are the same.
Can someone tell me the reason and how I can solve it? Thanks.
