Since your stack trace has no debug symbols it is hard for us to tell exactyl
what's going on here.

If you use the libcurl API as documented, there should be nothing else to
free.

I can't tell because there's not enough information. I would prefer a
stand-alone source code that can reproduce the problem or if that's too hard,
maybe you could at least run a debug-version of libcurl with the symbols
present so that we can see a more descriptive stack trace there?

How often do you experience this leak? Do you know any triggers that make it
more likely to happen?

I don't think we have any known such memory leak (fixed since 7.68.0).
