Maybe the Linux distribution you are using, the processor type (`cat
/proc/cpuinfo`) / architecture (`uname -a`) and last but not least the
version of GCC (`gcc -v`).
If you haven't yet run Sage's test suite, you could at least run a subset
of it:
{{{
#!sh
/home/float/sage$ ./sage -t -long devel/sage/sage/libs/pari/
...
/home/float/sage$ ./sage -t -long devel/sage/sage/interfaces/gp.py
...
}}}
(Both together should ''at most'' take a few minutes on a slow machine;
the second one doesn't make much sense if the error also occurs in plain
PARI/GP as you said.)
Probably more important, as this seems to be an upstream bug, you can run
''PARI's'' test suite, which unfortunately requires rebuilding PARI, and
hence will take much more time (up to 30 minutes I think, depending on
your machine):
{{{
#!sh
/home/float/sage$ env SAGE_CHECK=yes ./sage -f -s pari-2.4.3.alpha.p5 2>&1
| tee pari-test.log
}}}
(This reinstalls the package unless PARI's test suite fails, and logs the
output to `pari-test.log`. If you end up with a broken Sage installation
because the test suite didn't pass, you can reinstall it by almost the
same command, simply omitting the `env SAGE_CHECK=yes` and optionally
`-s`, i.e. `./sage -f pari-2.4.3.alpha.p5`.)
