      When debugging a core dump, there are a handful of warnings like

      $ /opt/mongodbtoolchain/v5/bin/gdb ./bin/db_s_resharding_part2_test ./dump_db_s_resharding.322211.core
...
Reading symbols from ./bin/db_s_resharding_part2_test...

warning: .gdb_index address table has a range (0xbc93a - 0xbc93b) that overlaps with an earlier range, ignoring .gdb_index

warning: core file may not match specified executable file.
...
warning: .gdb_index address table has a range (0x7b937 - 0x7b938) that overlaps with an earlier range, ignoring .gdb_index

warning: .gdb_index address table has a range (0x8dc2e - 0x8dc2f) that overlaps with an earlier range, ignoring .gdb_index

warning: .gdb_index address table has a range (0x8a36d - 0x8a36e) that overlaps with an earlier range, ignoring .gdb_index

      While these didn't obviously cause any function problems themselves, we should ensure they are innocent and consider silencing them. If they are a real problem, we should of course address their source.
