Good question. `main` should be one case if it hit any samples. In my run, it showed like below. seems it's from external lib.

  jemalloc_je_edata_heap_insert
  jemalloc_je_arena_dalloc_bin_locked_handle_newly_nonempty
  jemalloc_je_edata_heap_remove_first
  jemalloc_je_arena_cache_bin_fill_small
  extent_record
  _ZdlPvm

Not sure why this doesn't have context.
