5.7.2.5 Differences between named common and blank common (F2008, 5.5.2.4 for f95) ... Named common blocks of the same name shall be of the same size in all scoping units of a program in which they appear, but blank common blocks may be of different sizes. For the test in comment #6, the common should be blank one to make the test valid (detected with -Wall). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37486
