Not a lot we can do with that level of detail. Can you provide a
self-contained test case? (That is, besides the query, we need the
table definitions and some possibly-dummy data. Ideally, provide a
SQL script that provokes the crash starting from an empty database.)
It'd also be quite useful to know what build options you used.
Notably, I'm wondering about whether you enabled JIT (--with-llvm).
