-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gooood question. The corresponding lines look something like [1] (while iterating over the tags in the current set of items):
BOOST_FOREACH(const tag_t &my_tag, _tags) { ... else if(pmt::is_null(_length_tag_key) && pmt::equal(key, SOB_KEY)) { if (my_tag.offset != samp0_count) { max_count = my_tag_count; break; } // Bursty tx will not use time specs, unless a tx_time tag is also given. _metadata.has_time_spec = false; //(wut) _metadata.start_of_burst = pmt::to_bool(value); } ... and that (wut) might be a bug, because it implies that, if the stream has both a time tag and a sob tag, the question whether the tx metadata has a time tag depends on in which order these tags are sorted on the the tag storage multimap. Which might be random, because tags are sorted only by tag offset. @Martin: is there a reason that this is explicitely set to false here, or can one just fix this by deleting a line?
