Do you have an example program that demonstrates the problem?

I think the easiest way would be to checkout the commit just before that
and test it. Then check out that commit and test it and see if the first
commit worked while the second one failed.

e.g.:

$ cd src/curl
$ git checkout c43127414d89ccb9^
$ git clean -xdf # This will wipe out
any local changes in your repository.
[compile and test]
$ git checkout c43127414d89ccb9
$ git clean -xdf
[compile and test]
$ git checkout master

If things had been done correctly, those wrong connections should be
