Package: octave2.9
Version: 2.9.4-13
Your package fails to build with GCC 4.2. Version 4.2 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning. While the compiler error is
obviously not your problem (reported as #361602), it seems there are
some bugs in your package as well. You can reproduce this with the
gcc-snapshot package.
