Neither of these has been merged yet so should > not affect master? You are right.... I looked at commits that jenkins had as changes since the first moment things still executed oke. From there I looked for buffer/mempool/.... stuff, and saw that Sage had commit some stuff. So I checked his PRs in github, and found these two. What I did not look at, was wether the PRs were commited. :) So 15402 is a going to be fix for a problem that exhibits it sell on FreeBSD.
