Thanks Jeremy for reporting the issue!

What happens on HEAD?  That would be the target branch for a new
feature.

Just tested and i can see the same issue on HEAD.

Issue is on stmt->name being NULL here:

Breakpoint 2, JumbleExpr (jstate=0x55d60e769e30, node=0x55d60e769b60) at queryjumble.c:364
364             if (node == NULL)
(gdb) n
368             check_stack_depth();
(gdb)
374             APP_JUMB(node->type);
(gdb)
376             switch (nodeTag(node))
(gdb)
398                                     VariableSetStmt *stmt = (VariableSetStmt *) node;
(gdb) n
400                                     APP_JUMB_STRING(stmt->name);
(gdb) p stmt->name
$1 = 0x0

I'll have a closer look.
