[Bug libfortran/23154] New: Bad floating point in formatted read

[jvdelisle at gcc dot gnu dot org]

The following test case results in a floating point read error.

      DOUBLE PRECISION XIN, YIN, ZIN, WIN, QIN
      CHARACTER*4 SID, RID, RID2, REN, IUP
      CHARACTER*5 A

      CHARACTER*132 COMLYN

      COMLYN = "            abcd efgh jklmn      1.2345.678     21.765  2.34
     &  3.45xxxxxxWXYZ"

      PRINT *, COMLYN
      READ(COMLYN,'(12X,A4,1X,A4,1X,A5,3X,3F8.3,F6.2,F6.2,6X,A4)'
     &           ) IUP,REN,A,XIN,YIN,ZIN,QIN,WIN,SID
      STOP
      end

Possibly related to NIST formatted I/O and pr22570

I have instrumented a few places in transfer.c.  In particular looking at the
string at 'q' in sf_read.  The original string is corrupted before getting to
the first read.

Created an attachment (id=9389)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=9389&action=view)
Revised test case to honor 72 column magic

The revised test case here, remembering not to exceed 72 columns with the
important text no longer shows the problem.  So this testcase does not reflect
the situation in the original problem.
