Bug#916234: depending software build failure (arm64, armel, mips)

[Filippo Rusconi]

Package: libeigen3-dev
Version: 3.3.5-2
Severity: serious


Greetings, 

when building libpwiz on the arm64, armel, mips architectures, the build fails
with the following error:

In file included from /usr/include/eigen3/Eigen/SparseCore:50,
                 from /usr/include/eigen3/Eigen/Sparse:26,
                 from /usr/include/eigen3/Eigen/Eigen:2,
                 from pwiz/analysis/demux/DemuxTypes.hpp:24,
                 from pwiz/analysis/demux/DemuxDebugWriter.hpp:23,
                 from pwiz/analysis/demux/DemuxDebugWriter.cpp:20:
/usr/include/eigen3/Eigen/src/SparseCore/SparseBlock.h: In member function 'Eigen::internal::sparse_matrix_block_impl<SparseMatrixType, BlockRows, BlockCols>::BlockType& Eigen::internal::sparse_matrix_block_impl<SparseMatrixType, BlockRows, BlockCols>::operator=(const BlockType&)':
/usr/include/eigen3/Eigen/src/SparseCore/SparseBlock.h:216:33: error: expected primary-expression before '>' token
       return operator=<BlockType>(other);
                                 ^

Please, see 

https://buildd.debian.org/status/fetch.php?pkg=libpwiz&arch=arm64&ver=3.0.18342-1&stamp=1544522661&file=log
https://buildd.debian.org/status/fetch.php?pkg=libpwiz&arch=armel&ver=3.0.18342-1&stamp=1544523773&file=log
https://buildd.debian.org/status/fetch.php?pkg=libpwiz&arch=mips&ver=3.0.18342-1&stamp=1544524240&file=log

I am not positively sure that this package is guilty, but I cannot see another
bug reporting route at the moment.

Sincerely,
Filippo
