Comment (by raimue):

 No, this is a different problem. Yes, #56195 will solve it for the cargo
 port, but this is still a bug in cargo itself. Remember cargo can be used
 for development and not only for building ports. That this bug triggers in
 a port build is just a coincidence.

 cargo includes a bundled copy of libgit2. Therefore this problem could be
 the same as in this upstream issue:
 https://github.com/libgit2/libgit2/issues/4350

 I recommend to report the problem to cargo upstream.
