double-free and possible memory leak in acb_dirichlet_hardy_z #421

Closed crowlogic closed 2 years ago

crowlogic commented 2 years ago

I ran into this working on arb4j and then when running very large renders getting my process crashed with no ram left.. when I enabled jemalloc it crashed on parts involving the Z function as well. I will look into this further
