------- Comment #3 from kargl at gcc dot gnu dot org 2007-01-08 18:55 ------- This is related to an undocumented warning flag. In options.c, gfortran sets several warnings to on. One of these is
gfc_option.warn_character_truncation = 1; If I change this to 0, then your code with -Wall compiles. Fortunately, gfc_option.warn_character_truncation appears only in decl.c and resolve.c, and occurs exactly once in both files. A few things need to occur: 1) Add a -W[no-]character-truncation option. 2) Document the option. 3) Fix Martin's bug -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30408
