First off, thank you for organizing these build failures into bugs. This is great, and makes things much easier for me. There is a CMake variable to turn off eigen alignment in OpenSurgSim, and I have pushed a change that turns it off for i386 and powerpc to the package repository [1]. I also turned on some more unit tests that more aggressively test Eigen, to make sure we are ok on the other architectures. I'll push out a new version of OpenSurgSim soon with these changes. Thanks, -Paul [1] https://anonscm.debian.org/cgit/debian-med/opensurgsim.git/commit/?id=69a076e667dbf776369fba2876052f66282b2c7d
