Subject: [PATCH 2/2] defs.h: fix breakage of compatibility of struct
|
|
|
b2ff16 |
symbol_table_data for extension modules
|

Commit <3ab39203ddd9> ("symbols: Implement install and remove operations
|
|
|
b2ff16 |
for mod_symname_hash") added new member variable mod_symname_hash in the
|
|
|
b2ff16 |
middle of struct symbol_table_date, which breaks compatibility of struct
|
|
|
b2ff16 |
symbol_table_data for extension modules. As the result, crash trace command
|
|
|
b2ff16 |
results in segmentation fault.

Fixes: 3ab39203ddd9 ("symbols: Implement install and remove operations for mod_symname_hash")
