[Bug fortran/85896] ICE in gfc_convert_constant(): Unexpected type

[gscfq@t-online.de]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85896

--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---

This variant should not compile :


$ cat z3.f90
program p
   character(:) :: max
   print *, max('a','b')
end


$ gfortran-9-20180520 z3.f90 -static-libgfortran
$ a.out
 b


It's a regression since about 20171210 (20171203: ICE from above).
