I don't have this failure here when trying to install emacs23 (cscope is
also installed). Do you know if there are some more conditions to
trigger this bug?

Also, it looks like a memory corruption. Have you tried to reboot the
machine? A different kernel?

The testsuite has been disabled due to broken buildds, not due to a
broken package. It is actually run when build on a different machines
than the build daemons, and it passes without any problem, provided you
have a recent kernel (lenny one for example).
