Linux: DevShares build 0.5.0 crashes

[davidpbrown]

DevShares seems not to have /issues/new option on github so posting here.

Having build DevShares previously when it was in BitShares branch
Now, 0.5.0 build crashes at 100% on Linux Mint 17 and Ubuntu 14.10 i386

hmm.. I'm not used to github markup and can't attach a text file!

Error ends:

First of all multest.cpp is a benchmark / test. It is not required for normal usage, and should not be built unless you specifically ask for it. What make target are you using?

To copy stuff verbatim to Github markdown, indent it four spaces.

As for the actual compiler error, it should be fixed by 2602504 (n.b. this commit is on our bleeding-edge branch and needs ported to devshares).
