--- Comment #5 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-08-17 13:05:07 UTC --- To continue tracking: Bill Long (Cray) thinks that "******" (i.e. the current gfortran behaviour) is correct as: "The key point here, which does not show up in email font, is that, in the standard, the "w" in the phrase "entire field of width w" is in syntax font. For G format, this ties to the line of R1007 noted above. The value of w is clearly 6 here. That's what appears in the program." Cf. http://j3-fortran.org/pipermail/j3/2011-August/004580.html
