Thanks for releasing 3.3~alpha1.

There is a compilation error on x86_64, gcc-5.2.1

==================
[1] cd "/«PKGBUILDDIR»/debian/build/doc/snippets" &&
../compile_MatrixBase_ones
>/«PKGBUILDDIR»/debian/build/doc/snippets/MatrixBase_ones.out

Illegal instruction
==================

Full log is here [1]. On powerpc it compiles just fine.
