REDHAT-BUG-2167498
First published: Mon Feb 06 2023(Updated: )
In Binutils, the field `file_table` of `struct module *module` is created without being initialized, and then its uninitialized field is used to assign `*file`, which is a pointer to a global variable `filename`. Later on when this variable is used, a segmentation fault occurs.
