which version of sci-mathematics/pari do you have installed? (curious)
sci-mathematics/pari-2.1.7-r1 that package has textrels, bug 143764
Because math-pari builds with a side by side copy of the source from sci-math/pari, can we hold off until the sci folks have a chance to look at pari? (I'm suspecting their fix will at least carry over in part if not full)
looks like this was resolved back when sci-math/pari was resolved. please reopen if this is still occurring for you.

On hardened system, after upgrade from 2.6.26-hardened-r9 to 2.6.27-hardened-r8, every perl script which 'use Math::Pari' will crash with segfault. To work around either (if you need Math::Pari): # work around 'text file busy' error: cp /usr/bin/perl5.8.8 /usr/bin/perl5.8.8.tmp paxctl -m /usr/bin/perl5.8.8.tmp mv /usr/bin/perl5.8.8.tmp /usr/bin/perl5.8.8 or (if it usage optional): rm /usr/lib/perl5/site_perl/5.8.8/i686-linux/auto/Math/Pari/Pari.so Both ways are bad - either relax PaX protection for all perl scripts or stop using Math::Pari. :( I think severity should be changed to 'critical'. P.S. The interesting question - why what happens only after kernel upgrade? Maybe that's because of some PaX improvements in 2.6.27 kernel?

This should be fixed in =dev-perl/math-pari-2.01080601 which uses pari-2.3.4. Also tests do not fail with this version.
