Comment(by vbraun):
Well this is a spectacular bandaid to work around compiler breakage :-)
* Having hard-coded memory and time limits will just create problems
down the road as pari is bound to get bigger, gcc is going to use more
ram, and people try this on a wider (slower) range of hardware.
* We apparently know that optimization of Pari is not working correctly
on gcc 4.4.1 yet we still build it with optimization and hope for the
best? What could possibly go wrong?
How about we disable optimization (or set a known-good value, maybe `-O1`)
if the compiler is gcc-4.4.1. Unless you set `SAGE_PARI_tune=yes`, in
which case we'll still build it with all optimizations turned on. That
way we are on the safe side and the workaround will become unnecessary
over time as people upgrade to newer gcc releases.
And if you know what you are doing you can easily override it.
