There’s a suggested patch for this in https://github.com/nothings/stb/pull/1995, but it was rejected without comment, presumably because it was drafted with AI/LLM assistance. The patch is straightforward enough and appears sensible enough to consider applying it downstream. Nothing in Fedora currently depends on the stb_sprintf library subpackage.
