Relatively clean Linux Mint 17 old laptop but it complied ok. 0.4.7 worked fine. It's just 0.4.8 that falls over within ~10mins of downloading the blockchain, regardless of whether it's a clean new wallet or the old one.
I've got log files which are peppered with Bad file descriptors and alsorts.. but not sure what to make of those. Sample of the end of p2p.log below from line 17523. I don't know, if the last line is useful..
