Hi all,
is there something, on top of the llvm packages, I shall test or provide to help the root cause be analyzed?
If I understand the patch properly, I'll avoid SIGSEV, but still the query with jit=on will fail, except (which is a significant improvement!) the server will not be restarted.
Thanks Ales

Oh! So it's (probably) not a Memoize problem, it's an LLVM problem.

Hm. What LLVM version have you got on that machine? (And I wonder
whether it's the same as what Devrim built this PGDG package against.)
