Hello, I have to admit I'm clueless about how to debug this. On Fedora 11 preview release with gcc-4.4.0 alpine "reply to all" does not include the list of cc'd addresses. Linus found that if you compile the pith/reply.cc without optimizations it works properly (see Fedora bug report at http://bugzilla.redhat.com/show_bug.cgi?id=496400 ).
Here is how to reproduce: mkdir alpinetest cd alpinetest svn checkout https://svn.cac.washington.edu/public/alpine/snapshots/ cd snapshots _sysconfdir=/etc/ touch imap/ip6 ./configure \ --enable-debug=no \ --without-tcl \ --with-c-client-target=lfd \ --with-passfile=.alpine.passfile \ --with-spellcheck-prog=aspell \ --with-system-pinerc=%{_sysconfdir}/pine.conf \ --with-system-fixed-pinerc=%{_sysconfdir}/pine.conf.fixed make alpine/alpine # try "Reply to all" and see bug cd pith make clean && make CFLAGS=-O0 cd .. make alpine/alpine # try "Reply to all" and see it working -- Summary: 4.4 regression breaks "reply to all" in alpine Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: joshuadfranklin at yahoo dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40022
