+Subject: [PATCH] Fix stack overflow in CVE-2023-31922
+
+isArray and proxy isArray can call each other indefinitely in a mutually
+recursive loop.
+
+Add a stack overflow check in the js_proxy_isArray function before calling
+JS_isArray(ctx, s->target).
+
+With ASAN the the poc.js from issue 178:
+
+```
+./qjs ./poc.js
+InternalError: stack overflow
+  at isArray (native)
+  at <eval> (./poc.js:4)
+```
+
+Fix: https://github.com/bellard/quickjs/issues/178
