--- Comment #3 from ishikawa,chiaki <ishikawa at yk dot rim.or.jp> --- https://send.firefox.com/download/bdf77223953903fa/#WMrJbMYdsL7AXf2vXYm82g I uploaded the file, UnifiedBindings23-v7.cpp, to the link above. It is huge as I explained. Approximately 28MB. The compiler options I used for each version of the g++ compiler is in the attachment: https://gcc.gnu.org/bugzilla/attachment.cgi?id=48380 -ftime-print log for V9, V8 and V7 g++ compiler compiling preprocessed UnifiedBindings23.cpp Since the file was already preprocessed, -I options won't have any meaning, but I simply copied from the original build command. Thank you again for your attention on this matter.
