Hi
I have a reproducable crash on i386 using the 25-May-2012 snapshot on my ARP
Networks VPS. This is a vanilla kernel with the exception of disabling mpbios.
To reproduce, build the net/bitcoin port posted by Pascal Stumpf to ports on
26-May-2012. Create a ~/.bitcoin and bitcoin.conf with the the basic stubs:
mkdir -p ~/.bitcoin && cat >.bitcoin/bitcoin.conf
rpcuser=bitcoinrpc
rpcpassword=BNXfRA79vWDHeon2wXxxe9htAkrcicSdRmLb1QWspXYM
^D
Start bitcoind using bitcoind -daemon, give it a few seconds before killing
it using bitcoind stop. rm -rf ~/.bitcoin/* and repeat from the top a couple of
times.
This results in the following:
uvm_fault(0xd5b03804, 0x0, 0, 1) -> e
