SELinux is preventing /usr/bin/gdb from 'write' accesses on the directory /usr/share/glib-2.0/gdb.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If you want to allow gdb to have write access on the gdb directory
Then you need to change the label on /usr/share/glib-2.0/gdb
Do
# semanage fcontext -a -t FILE_TYPE '/usr/share/glib-2.0/gdb'
where FILE_TYPE is one of the following: gconf_home_t, pcscd_var_run_t, xkb_var_lib_t, xdm_rw_etc_t, xdm_home_t, pam_var_console_t, cgroup_t, var_lock_t, root_t, tmp_t, var_t, user_home_dir_t, locale_t, var_auth_t, user_fonts_t, user_tmpfs_t, tmpfs_t, xdm_spool_t, fonts_cache_t, user_tmp_t, auth_cache_t, xdm_tmpfs_t, var_spool_t, var_lib_t, var_run_t, xserver_log_t, xdm_tmp_t, var_log_t, xdm_log_t, gnome_home_type, pam_var_run_t, xdm_var_lib_t, xdm_var_run_t. 
Then execute: 
restorecon -v '/usr/share/glib-2.0/gdb'


*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that gdb should be allowed write access on the gdb directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep gdb /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
