The following code fails to compile:
std::tr1::shared_ptr<const sbuild::chroot_facet_session> psess;
psess = this->chroot->get_facet<sbuild::chroot_facet_session>();
However, this code compiles without error:
std::tr1::shared_ptr<const sbuild::chroot_facet_session> psess;
psess = chroot->get_facet<sbuild::chroot_facet_session>();
The only difference is the deletion of the "this" pointer. chroot is a member
of the class this method is a part of, and get_facet is a templated member
function of the chroot class.
I will attach preprocessed source for g++-4.3.3, 4.4.1 and 4.5.0 (recent SVN).
All three versions fail to compile this valid code. The output of g++ -v
-save-temps for all three compiler versions follows:
g++ -v -save-temps -DHAVE_CONFIG_H -I. -I.. -I../sbuild -I..
-I/usr/include/uuid -DTESTDATADIR='"./testdata"' -I../bin -pthread -pedantic

I removed all of the -f and -W options to see if this made any difference, and
it does not.
