Segmentation Fault on utree-search_gg

[bhillmann]

Using the most up to date utree-search_gg I receive a segmentation fault on the data from MSI. I haven't narrowed down if it is a specific read that is causing this issue or not.

Couple of things -- the way it's written in your log above is the old way. Is it possible you're using an old version by mistake? The newer version has no underscores in its name.

Also, the test file is very large (~200GB). It would be helpful to have a version that highlights the problem. One way to get at this is to take the first ~million sequences after the last sequence that failed to output properly in the .tsv file. Using this simplified subset I can hone in on the problem.

Cheers and thanks for the report! The GG version has gotten extremely little testing, so every little bit of info helps 👍

I verified that it is running with the new version of UTree search. The database may have been built with the older version of UTree. I'm not sure what version of UTree it was using for sure though for any steps. Any way we could incorporate a version string?
