Bug #: 56670
Summary: Allocatable-length character var causes bogus warning
with -Wall
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: towns...@astro.wisc.edu
Compiling this short test case with the -Wall option:
program uninit_test
implicit none
character(LEN=:), allocatable :: name_format
name_format = ''
end program uninit_test
...causes the following bogus warning:
uninit_test.f90: In function ‘uninit_test’:
uninit_test.f90:7:0: warning: ‘.name_format’ may be used uninitialized in this
function [-Wmaybe-uninitialized]
name_format = ''
^
(Note also that the warning arises in the main program, and not in a function
as the message suggests).
gfortran -v:
