format is const char * while to_free is non-const char * here.

Hmmm, did this even pass tests and if so how? What are these double
%% doing before refname and end? Perhaps we do not have enough test
coverage?

This assignment discards constness.
Take the result of xstrfmt() to to_free (which is a non-const
pointer) and then assigning it to format (which is a const pointer)
would work it around.
