Bug #: 56735
Summary: Namelist Read Error with question marks
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: madawilli...@gmail.com
Hi,
This is my first ever bug report so apologies if i miss some vital piece of
information. I have some legacy code which compiles and runs with versions of
gfortran up to 4.5. However after this the code compiles and runs but the
namelist is not read correctly. There is no IO errors but non of the variables
are set to their respective values. I have managed to narrow this down to the
fact that the legacy namelist has question marks in the namelist file outside
of any data block. Below is a very simple code and namelist which shows this.
If you remove the question mark from the name list the values are set,
otherwise they are not.
-test.f
PROGRAM TEST
INTEGER int1,int2,int3
NAMELIST /temp/ int1,int2,int3
OPEN (53,FILE='test.nam',STATUS='OLD', IOSTAT=istat)
READ (53,temp)
WRITE(*, temp)
PRINT*, istat
END PROGRAM
-test.nam
?
$temp
int1=1
int2=2
int3=3
$END
I understand this might be non standard formatting for the namelist file, but
as I said it works with gfortran <4.6 so seems like a regression.
