Compiling with -fno-tree-pta makes it behave as "expected". I do not believe the compiler to be at fault here. PARI is clearly full of undefined behaviours they really ought to fix rather than complain that doing so would change the ABI and blame the compiler which is only doing a good job following the spec.
