I found a very handy way of bisecting for gfortran changes, when working on
PR124845:

1] Do a diff to a commit, where is know that what is now working did not or
vice versa;
2] Copy and paste the fortran part of the diff; and
3] With the help of the ChangeLog, bisect the diff.

This obviously works best, or even at all, with patches over multiple files and
so this is where the ChangeLog helps.
