help with core dump? | Bitcointalksearch.org

Hey,

I have a private git version that is based on the public git with a few personal patches that should be fairly innocuous and everything was just fine. I have a few remote miners working with this daemon, and the big change I did is that I don't need the miner login to match the rpcuser (but still need to correct password), so I can log which miner is doing the getworks. I've also got everyone working over ssl.

But since yesterday, for some reason, bitcoind keeps dying out of the blue. I grabbed a core dump and I wonder if anyone can help me here.

I've since updated to the latest git (bf3a0902ef98365d803e4a03853dbf0f83511026) compiled locally, but same thing happens

Code:
