The only way to deal with it is a complete lockdown of gfortran for six months.
If nobody uses it, the number of bugs will surely drop. Then the roadmap out of
lockdown should start with only F95 being allowed, then six months later F2003
and so on. If at any stage the R number goes above unity, we revert one step in
the roadmap.
