+            (WASMModuleInstanceCommon *)module_inst);
+        shared_heap_end_off = get_last_used_shared_heap_end_offset(
+            (WASMModuleInstanceCommon *)module_inst);
+        native_addr = shared_heap_base_addr_adj + app_buf_addr;


Given that shared_heap_base_addr_adj could potentially be NULL, we should move this line into the if(shared_heap_base_addr_adj) block around line 1376.

It won't be NULL if is_app_addr_in_shared_heap holds true, I will move the 1376 block here
