With some code (attached) using an anonymous namespace I get an unexplained
"<anonymous> is used uninitialized in this function" with -Wall, with no
indication of what is seen to be used uninitialized. Changing the namespace to
a named one removes the error, as does removing part of the body of a used
method.
g++ (GCC) 4.4.0 20090506 (Red Hat 4.4.0-4)
-DTEST1 names the namespace
-DTEST2 comments out the body of the offending method
"wiggling" the code makes it disappear/reappear, but difficult to know what the
problem is so as to make the test-case a more reasonable size
$ g++ -O2 -c -Wall foo.cxx
foo.cxx: In function bool demo():
foo.cxx:4033: warning: <anonymous> is used uninitialized in this function
foo.cxx:4033: note: <anonymous> was declared here
$ g++ -DTEST1 -O2 -c -Wall foo.cxx
$ g++ -DTEST2 -O2 -c -Wall foo.cxx
Looks similar to bug #38908 but that one compiles without warnings here
