--- Comment #2 from ishikawa,chiaki <ishikawa at yk dot rim.or.jp> --- Created attachment 47964 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47964&action=edit The script to issue gcc-9 with the original option setting. This is the command to invoke gcc-9 on my PC with the original option. The preprcessed source needs to be copied under /tmp directory. Also, it tries to compile t-format-issue.c (I called it incorrectly in my original post), which it succeeds to do so.
