When add below line to local.conf to enable debug build:
DEBUG_BUILD = "1"
There comes below failure when run "bitbake babeltrace2"
| ../../../../../git/src/plugins/ctf/fs-src/fs.c: In function
'ds_index_insert_ds_index_entry_sorted':
| ../../../../../git/src/plugins/ctf/fs-src/fs.c:702:5: error: 'other_entry'
may be used uninitialized in this function [-Werror=maybe-uninitialized]
| 702 | !ds_index_entries_equal(entry, other_entry)) {
So initialize the other_entry pointer to fix the above error.
