I cannot readily reproduce this.
Which version of Postgres is this and on which platform/distribution?
It was tested on master branch (pg 17) on Fedora 39
Did you try keep jit on but set jit_inline_above_cost to 0?
The back-branches have a fix for the above case, i.e. llvmjit memleaks that can be worked-around by setting jit_inline_above_cost=0.
