[Bug fortran/29147] New: Overflow check in DATA statements

[anlauf at gmx dot de]

Hi,

a recently introduced range check not only kills
legacy code that I use, but also gives a misleading
error message:

% cat gfcbug42.f
      INTEGER IBALL(4)
      DATA IBALL / Z'FF'        ,
     +             Z'FFFF'      ,
     +             Z'FFFFFF'    ,
     +             Z'FFFFFFFF'  /
      END
% gfortran -c -std=legacy gfcbug42.f
 In file gfcbug42.f:5

     +             Z'FFFFFFFF'  /                                       
                             1
Error: Arithmetic overflow converting INTEGER(8) to INTEGER(4) at (1)


Funny, I even do not see any 8 byte integer around...
