The below is a direct copy-paste from my terminal:
[Brads-MacBook-Pro:~/tmp/ice_mwe] cat mwe.f90
implicit none
type VARYING_STRING
character(len=1), allocatable :: characters(:)
end type
interface operator(==)
procedure character_EQ_String
end interface
print *, stringToChar(var_str("Hello")) == var_str("World") ! causes ice
contains
logical function character_EQ_String(lhs, rhs)
character(len=*), intent(in) :: lhs
type(VARYING_STRING), intent(in) :: rhs
character_EQ_String = lhs == stringToChar(rhs)
end function
function stringToChar(string)
type(VARYING_STRING) string
character(len=size(string%characters)) :: stringToChar
stringToChar = ""
end function
type(VARYING_STRING) function VAR_STR(char)
character(len=*) char
integer i
VAR_STR%characters = [(char(i:i), i = 1, len(char))]
end function
end
