New description:
1. GCC 4.6.3 miscompiles `src/language/init.c` on OS X 10.4 PPC (32-bit),
because of a problem with pointer arithmetic in `stack_base()` called in
`pari_init_functions()`. There is an easy work-around by reordering some
code in the PARI sources. Related to #12369.
This is upstream bug [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49330]
-----
2. PARI's `ispower()` function gives wrong results when applied to
negative numbers. Related to #12116.
This is fixed upstream [http://pari.math.u-bordeaux.fr/cgi-
bin/bugreport.cgi?bug=1302]
