From readme:
legacy compile info
This version will work on all cpus, but was compiled with support for old/ancient cpus.
Should work on any cpu down to a pentium 2. It runs slightly slower than the normal version as
it does not use SSE instructions/prefetching.

Bug has been fixed and verified by Ray, probably tomorrow there will be a new version 2.3.1. We are now finishing testing a last minute patch from Gary that should increase ELO a bit and we would like to commit in.

Stockfish 2.3.1 update available

Jim Ablett wrote:

Stockfish 2.3.1 JA by the Stockfish Team

This update fixes the chess960 bug.

1) For people compiling themselves the Stockfish bench signature is: 5423738
It means that if you run ./stockfish bench then it should show 5423738 nodes searched.
This means that the compile is correct.

2) For people running / using under Android / iPhone with more than one thread,
I'd suggest to set "Use Sleeping Threads" option.
This allows to save power and battery and strength is practically the same.

Jim posted this at talkchess,

Yes it crashed for me too. I found the GCC optimizations that were causing the crash. It was the Graphite loop transformation switches '-floop-interchange' , '-floop-strip-mine' & '-floop-block'. A pity really as these gave a small speedup when used.

I will recompile the 64 bit versions and post them here when done.

No problem with the Linux versions which use identical switches.
Makes me think this is a compiler bug in Mingw compiler although my Windows builds still run faster than Linux ones on same machine without graphite loop optimizations.
Anyway I have recompiled the 64 bit windows versions. Very very slightly slower than before on my machine but your mileage may vary.
