arma323.ii.gz

Retested with gcc 4.7.1 and Armadillo 3.2.3 (latest upstream version).

This time a related but different bug in GCC is exposed.
arma323.ii.gz is the attached pre-processed source.

Code compiles fine on gcc 4.4.6 and clang 3.0.

GCC 4.7.1 was compiled directly from sources, using GCC 4.7.0 on a Fedora 17
machine.

/usr/local/bin/g++ -v
