If i attach the regression log , would that help ?
Nope, because it's not important how you get to the faulty commit. And putting here other unrelated commits may affect someone else search.
Rather verify, that you found the right commit. There are multiple ways, how to perform verification, but for example:
git checkout -f faulty_commit recompile //here you have to see the problem
git show faulty_commit | patch -p1 -R recompile //here your application behaves correctly
