(That's me.)

I'm not familiar with Ubuntu's bug reporting system, so someone who
works on the distribution (in MOTU, I guess?) will have to forward this
comment along to it.

If I am not mistaken, this looks like Debian bug # 324902, for which a
log is available at http://bugs.debian.org/324902 .  The culprit of this
bug was a compiler problem, which I reported here:
http://bugs.debian.org/325050 .  So I think the only fix, unfortunately,
is to recompile your package of PAW with a compiler not having the bug.

To recompile the Debian Way (TM), which I guess is the same as the
Ubuntu way, I provide some instructions on the Cernlib in Debian FAQ
page, http://people.debian.org/~kmccarty/cernlib/faq.html , specifically
question 2.2.  Before recompiling, you'll want to install an older gcc
package, for instance "gcc-3.3", and make sure that /usr/bin/gcc is a
symlink to gcc-3.3 (for instance), not gcc-3.4 or gcc-4.0.  (Unless your
gcc-4.0 is newer than version 4.0.2-4, then you could use that as well.)

Alternatively I suspect that this should be fixed in the PAW package
currently available from the development version of Ubuntu, Dapper
Drake, if you're willing to use that.

I hope this helps you.

best regards,
