I checked quickly, there's an assertion error with the daemon built as 'release'. I got it working as it does when built as 'debug'. No issue with gcc4.8 -> gcc5.*

GCC is now up to v7.1.1 (on Arch-Linux at least), so I hope that the way to resolve this is at least compatible with newer versions.

I tried building with GCC v5.3 via a PKGBUILD I made, but on the Arch repo's GCC seems to have broken links (to the GNU servers), which result in a failed installation. I can't really find a resolution to this, short of creating my own GCC v5.3 pkgbuild from scratch, and require that PKGBUILD in a custom PKGBUILD to build Vcash, but that's a ton of work that I honestly don't fully understand how to do.

To avoid this issue you can sudo pacman -S gcc5 which will install gcc-5 5.4.0-1 alongside the latest gcc 7.1.1-2. The only change you have to make is in nearly the last line of the build script ../../deps/boost/bjam -j$job toolset=gcc cxxflags=-std=gnu++0x release | tee -a $VCASH_ROOT/build.log by changing the toolset=gcc to toolset=gcc-5.
