Bug ID: 98558
Summary: Scalar character parameter does not print warning if
actual length >1
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: federico.perini at gmail dot com
Target Milestone: ---
Created attachment 49898
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49898&action=edit
test program
More of a suggestion than a bug (I don't see memory issues).
If I initialize a CHARACTER, PARAMETER variable with a string whose lenght is
>1, no warnings are printed in gcc/gfortran 9.2.0:
program test_char_parameter
implicit none
character , parameter :: a = 'a' ! OK
character , parameter :: b = 'bbbbb' ! NO -> No warnings printed!
character(len=1), parameter :: c = 'ccccc' ! NO -> No warnings printed!
character(len=*), parameter :: d = 'ddddd' ! OK
print *, a
print *, b
print *, c
print *, d
end program test_char_parameter
Best,
Federico

What options are you using?
% gfcg -c -Wall b.f90
b.f90:4:40:
4 | character, parameter :: b = 'bbbbb' ! NO -> No warnings printed!
| 1
Warning: CHARACTER expression at (1) is being truncated (5/1)
[-Wcharacter-truncation]
b.f90:5:40:
5 | character(len=1), parameter :: c = 'ccccc' ! NO -> No warnings
printed!

My bad,
I haven't tested this with the warning flags on.
Thanks!
