Comment(by mmasdeu):
I have run all tests you suggested and everything seems ok. I have also
tried to run the code in another machine that has Sage installed (that is
an Intel Xeon with 8 cores, so quite different to my '06 laptop). That one
is running Sage 4.6.2 (2011-02-25). And got the same error.
Here is the data about my laptop (in which it is easiest for me to
experiment):
Distribution: Arch Linux updated a few hours ago (but I have seen the bug
weeks ago).

/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`.)
