PAW - Segmentation violation - Traceq lun = 0, level = 99

[Stan Thomas]

I am encountering a seg fault problem with the cernlib package PAW (Physics Analysis Workstation) on Ubuntu 5.10 (Breezy Badger).

Here is a simple example demostrating the problem. In the example, I am attempting to read in a tiny ASCII data file into an ntuple.

This problem appears to be unique to Breezy. I am running the same version of PAW on Redhat 9.0 (kernel 2.6.11.10). The same simple examples works fine.

(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,
