Issue: sci-visualization/paraview-5.11.0_rc2-r1 overwrites user's optimization (-O*).
Discovered on: amd64 (internal ref: ci)
unless there are known issues with -O* configured by the user, the build system should not overwrite -O*.
Created attachment 843117 [details]
build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)
Search for -O0 in the build.log
Anyway it looks identical to bug 886317 so I realized that it bundles vtk.
