Nice! What does the message from TSan look like? (The full message doesn't need to go in the commit message, but a snippet can help.)

I *think* (but am not sure) that there is an implied bug report in this comment, but I am not sure what that bug report is and how I can help with it! If you have a link to an issue tracker, thread, wiki page, or other pointer where I can learn more, then that might help me.

Nowadays (since v2.13.2~26^2~3, 2017-05-12), there is a BUG() function that you can use in place of die(): BUG("hashmap_get_size: size not set"); Thanks and hope that helps, Jonathan
