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
files in the upstream repository.

+// Test that the destructor for a temporary passed by value isn't run
+// until end of full-expression, as per [class.copy]:
+
+// Whenever a temporary class object is copied using a copy  constructor,
+// and  this  object  and  the copy have the same cv-unqualified type, an
+// implementation is permitted to treat the original and the copy as  two
+// different  ways of referring to the same object and not perform a copy
+// at all, even if the class copy constructor  or  destructor  have  side
+// effects....                                       In these cases,  the
+// object  is  destroyed  at the later of times when the original and the
+// copy would have been destroyed without the optimization.
+
+// Here, the temporary would be destroyed later than the parm, so either we
+// must suppress the optimization in this case or destroy value parms in the
+// caller.
