From 6968345893178d2750b8872055498d2a6010a861 Mon Sep 17 00:00:00 2001 From: HATAYAMA Daisuke Date: Wed, 8 Dec 2021 12:07:34 +0000 Subject: [PATCH 3/3] defs.h: fix breakage of compatibility of struct symbol_table_data for extension modules Commit <2fab8fbc0c4f> ("symbols: Implement install and remove operations for mod_symname_hash") added new member variable mod_symname_hash in the middle of struct symbol_table_date, which breaks compatibility of struct symbol_table_data for extension modules. As the result, crash trace command results in segmentation fault.
