When a component of a "custom" type is a character, taking a substring of it
triggers a warning about the variable being truncated (with -Wall). Maybe it is
not the correct syntax to get a substring out of a character component (still,
it works fine for printing, for example)?
$cat test.f90
PROGRAM test
IMPLICIT NONE
TYPE custom
CHARACTER(LEN=10) :: nom
END TYPE custom
CHARACTER (LEN=10) :: a
CHARACTER (LEN=2) :: b
TYPE(custom) :: c
a='1234567890'
b=a(1:2)
c%nom=a
b=c%nom(1:2)
END PROGRAM test
$gfortran -Wall -c test.f90
test1.f90:13.14:
b=c%nom(1:2)
1
Warning: rhs of CHARACTER assignment at (1) will be truncated (10/2)
