--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-10-27 10:00:39 UTC --- That file is sufficient, but please attach it separately (the instructions at http://gcc.gnu.org/bugs/ are pretty clear about wanting preprocessed source not an archive that we need to extract to find the right file). N.B. preprocessed C++ source should use the extension .ii so GCC knows what to do with it, see http://gcc.gnu.org/onlinedocs/gcc/Overall-Options.html - if you use -save-temps as suggested at http://gcc.gnu.org/bugs/ then that file is created automatically
