SUMMARY: AddressSanitizer: 49143 byte(s) leaked in 184 allocation(s). The docs for `g_source_add_child_source(source, child_source)` says "source will hold a reference on child_source while child_source is attached to it." Therefore, we should unreference the child source at `qio_channel_tls_read_watch()` after attaching it to `source`. With this change, ./tests/unit/test-io-channel-tls shows no leakages.
