https://github.com/litecoin-project/bitcoinomg/commits/0.8.5-OMG6 http://download1.rpmfusion.org/~warren/bitcoin-0.8.5-OMG6/ I've been backporting patches from master and Litecoin to make a Bitcoin 0.8 client with more features. It works quite well on Linux and Win32. http://pastebin.com/g8QqheGc Today we discovered a rare crash that can happen on MacOS X. toffoo and coblee reproduced it on MacOS X 10.9 and I reproduced it on 10.6.8. It seems to be some kind of race condition involving SendCoinsEntry::clear(). 1. 11 QtGui 0x00e28141 QWidget::setFocus(Qt::FocusReason) + 289 2. 12 org.bitcoinfoundation.Bitcoin-Qt 0x002ca665 SendCoinsEntry::clear() + 101 This build was made with Xcode 3.2.6 on MacOS X with MacPorts qt4-mac qt-4.8.4, roughly meant to approximate Gavin's build environment for the 0.8.x releases. With this unfamiliar build environment I have been unsuccessful at building master so I am unable to confirm if this crash exists there. I am trying qt-4.8.5 next ... but even if I manage to build it, it is exceedingly difficult to reproduce... Warren
