Boost problems in nextsim base image

[einola]

I'm trying to run valgrind in a nextsim docker container, but it doesn't work anymore. The point is to try to track down the memory leak I may have introduced in a local branch (or maybe it was there before - it's a bit hard to tell).

I found that I can run valgrind on version 7925f86, but not on 996396b. They're quite close in time and a diff between the two points to the nextsim_base and nextsim_base_dev images (see below). The error I get is related to boost, so I'm guessing you updated boost in the nextsim_base image, compared to nextsim_base_dev. Right? Or is it the other way around - I'm confused as to which one of the two is more up-to-date.

Can you update boost again in the nextsim_base image and then I can try again and see if valgrind runs? If it doesn't, then we should downgrade to the version used in the original nextsim_base image.

For now, I'm using --build-arg BASE_IMAGE=nansencenter/nextsim_base_dev:latest. It works, but that's not optimal for the long run.
