Linus reported that sometimes 'perf report -s symbol' exits without any message on TUI. David and Jiri found that it's because it failed to add a hist entry due to an invalid symbol length. It turns out that sorting by symbol (address) was broken since it only compares symbol addresses. The symbol address is a relative address within a dso thus just checking its address can result in merging unrelated symbols together. Fix it by checking dso before comparing symbol address.
