Bug ID: 109080
Summary: A write of a NAMELIST group containing an allocatable
array is incorrect
Product: gcc
Version: 11.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: urbanjost at comcast dot net
Target Milestone: ---
Sometimes it runs and writes out ALINES incorrectly,
and sometimes the same executable segfaults.
program gnubug
implicit none
character(len=2) :: lines(3)
character(len=2),allocatable :: blines(:)
character(len=:),allocatable :: alines(:)
namelist/args/lines, alines, blines
lines = ['Xx','Yy','Zz']
alines = ['Xx','Yy','Zz']
blines = ['Xx','Yy','Zz']
write(*,nml=args,delim='quote')
end program gnubug
gfortran xx.f90
$ ./a.out
&ARGS
LINES="Xx","Yy","Zz",
ALINES= 3*"Xx",
BLINES="Xx","Yy","Zz",
/
./a.out
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

--- Comment #1 from anlauf at gcc dot gnu.org ---
This seems to have been fixed in gcc-12.
I see valgrind errors with versions <= 11, but not with >= 12.
Can you please update?

A cannot update, but on https://godbolt.org I found 12.2 was available, and
it worked there, so I suppose this can be closed.

Closing, invalid in the sense that it has been fixed in a later version of
gfortran.
Report is appreciated regardless.
