I'm just filing this as an FYI because it looks like it's been moved to gh (by the Debian maintainer). Thanks! https://github.com/resurrecting-open-source-projects/stress/releases/tag/1.0.6
Closing, as bumped already to 1.0.7 in the mean time :-) https://github.com/gentoo/gentoo/commit/9536c11585bafe242bfca96e188f8948802ffab2
