This bug might not be what it seems as I'm only rebuilding media-gfx/enblend-4.1.3-r1 (previously built-on 23:24:46 2015.08.14.) while the installed media-libs/vigra-1.10.0 was last built 2 weeks before that enblend build (04:42:24 2015.07.29.) meaning that either enblend sources has silently changed (obviously unlikely as it would require new hashes for the ebuild to work at all) or what actually is broken is the VIGRA_SETIMAGEINDEX test itself. I'm on hardened/linux/amd64 profile but using only the hardened toolchain without grsec or anything like that other than vanilla Tomoyo and Yama and neither of thetwo seem to have been triggered in this case. My compiler is gcc (Gentoo Hardened 5.3.0 p1.0, pie-0.6.5) 5.3.0 and my arch is ~amd64. Reproducible: Always Steps to Reproduce: 1. emerge -v1 =media-gfx/enblend-4.1.3-r1 Actual Results: -- Performing Test VIGRA_SETIMAGEINDEX -- Performing Test VIGRA_SETIMAGEINDEX - Failed CMake Error at ConfigureChecks.cmake:69 (message): Vigra library too old
Created attachment 420776 [details] build.log.gz
Rebuilding vigra fixed the issue so I'll put it to down to C++ ABI break or something.
