verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective

+! { dg-do compile }
+! Test the fix for PR25029, PR21256 in which references to
+! assumed size arrays without an upper bound to the last
+! dimension were generating no error. The first version of
+! the patch failed in DHSEQR, as pointed out by Toon Moene
+! in http://gcc.gnu.org/ml/fortran/2005-12/msg00466.html
