I don’t know what is wrong with gcc-4.6. Though the problematic platform was Kubuntuu 12.04. I am know trying with Ubuntu 12.04 which uses gcc-4.6 to see if it is really a gcc problem or the platform! Good luck. But as a PS, I’m puzzled that you are using such old software, both GCC (on version 7) and Boost (on 1.65) – and Ubuntu too (on 16.04), known to be riddled with many Old Bugs. I would have thought that you would be much better off without those bugs (even if that adds a few New Bugs) by starting with all new current software. (If management objects, tell them there is a price for using obsolete software, and you are paying it now). Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830
