This was an interesting one to debug. The tests are (indirectly) using snprintf, and don't seem close to consuming the buffer size, but are sending a too-large size for the size_t value in snprintf, and that triggers truncation of the printed value somehow. Worse, the truncation behavior isn't consistent. See attached reproducer which shows the weird truncation behavior.
