Download now. My hashes are:

sha256: 3ec3bbb173b95b740f79baf28b286f978a8b243cb16062c1caa1a76d95ad6e13

Are they ok?

Sometime Miner crash .I dont know why I have to restart it. I Use Ubuntu and Debian .Event I upgrade to new verion , Still crash.

Software compiled from source.  With

cd src
gmake -f makefile.unix

When run for the first time, it downloads the block chain, and "works". But restarting it always dumps core.
Deleting the block chain and leaving only the wallet -- works again, then after restart it is dumping core again.
Seems it is not liking it's on disk block chain. :)

If a strack trace helps:

Previous frame inner to this frame (corrupt stack?)

tried few different compilers, same result. Also, why is it producing bitcoind excitable? :)

I am solo mine about 25 xeon machines to 1 wallet.dat. Can i problem with that?
May be better to use different wallet.dat on each machine?
Thanks.

Freetrade not sure but I think the first link is the old wallet.

The Google link good.

Outstanding job on the fast startup time!

Very cool! Incredibly fast start! Solved the main problem is frustrating me.

[I_M]

This is much better!  Startup was practically instantaneous!  Thanks!

New version available.

Windows Binaries and github source updated.

The main change is faster startup, reindex and better performance - previous hashes are cached so hashing is only ever performed once for a block.
