same for me
In the sample implementation I have "goto CLEANUP" and an implicit
guarantee that the output is always null terminated. This is more in
the spirit of `snprintf` not to do bad things as soon the output
buffer has at least 26 bytes.
But we could also do `abort()`, `do_crash()`, whatever fits into
musl's general strategy for error handling.
