[AzothAmmo]

Likely a dup of #280, this is related to boost 1.61.

[AzothAmmo]

I'm having trouble reproducing this on the develop branch. I think this was fixed by 1d50761 and 68f7508.

Can you checkout develop and let me know if this persists?

[xyproto]

The issue is now gone when building the develop branch (gcc 6.1.1).

There are other errors, but they seem to be unrelated to this issue: full output

[AzothAmmo]

Seems to be related to a new warning in GCC6 (-Wterminate, see here), probably worth its own issue.
