Not really, as the issue seems to complicated to condense into a bug
report.  From discussions with Thomas Koenig from the GCC team, it seems
that f2c, g77 and now gfortran have always added additional character
length arguments for each character argument, where the R
F77_NAME/F77_CALL mechanism has always called with the arguments of the
Fortran subroutine but without the additional length arguments.  A
change in gcc trunk also ported to gcc-8-branch apparently changed what
happened in such case, to the effect that we're now seeing about 25
CRAN packages fail their run time checks with segfaults or run time
errors ...

But things are actually hard to pin down for us, and no obvious "fix"
is in sight.  It would be great if at least for the gfortran-8 that
Debian will release we would get the old behavior back ...
