segfault on exporting 6.6GB array

[Dimitar Misev]

Attached is a script that establishes the array. The issue afterwards can be reproduced with

directql -q 'select encode(c, "jpeg") from test_coll_7GB_rgb as c' --out file

segfault stacktrace:

Query without encode also fails, at a different point but still in copyTile:

directql -q 'select c from test_coll_7GB_rgb as c' --out file
