Thanks for taking care of this and the other FTBFS bugs I reported!  In
reviewing the logs for 0.6.0-3, I see that this same error has surfaced
on ppc64el; could you please extend this fix to that architecture too?

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

Bug#798693: opensurgsim: FTBFS on i386 and powerpc: unaligned Eigen arrays

2015-09-11 Thread Aaron M. Ucko 
Source: opensurgsim
Version: 0.6.0-2
Severity: serious
Justification: fails to build from source

The i386 and powerpc builds of opensurgsim both failed because many
tests reported errors of the form 

SurgSim*Test: /usr/include/eigen3/Eigen/src/Core/DenseStorage.h:86: 
Eigen::internal::plain_array::plain_array() 
[with T = double; int Size = 16; int MatrixOrArrayOptions = 0]: Assertion 
`(reinterpret_cast(eigen_unaligned_array_assert_workaround_gcc47(array))
 & 0xf) == 0 && "this assertion is explained here: " 
"http://eigen.tuxfamily.org/dox-devel/group__TopicUnalignedArrayAssert.html"; " 
 READ THIS WEB PAGE !!! "' failed.

(The powerpc build also encountered an unrelated test suite error,
which I'll report separately.)

Could you please take a look?  Per the error message, you may find
