Package: octave2.1
Version: 1:2.1.73-2

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.  The bug below is in your package
and not because I'm using a snapshot of the compiler so please take a
look at it.  You can reproduce this with the gcc-snapshot package.

Same problem as octave2.9.

Thanks for the quick confirmation.  I am hereby closing this bug report, as
well as #362219 because the patch proposed by John is already present
in the octave2.9 package.
