--- Comment #9 from ishikawa,chiaki <ishikawa at yk dot rim.or.jp> --- Thank you for the confirmation for the fix in GCC-12. Now I have to figure out how GCC-12 seems to miscompile something in Thunderbird mail client to report a run-time assertion error. (Compiling Thunderbird mail client with earlier version did not show the runtime assertion error. So I wanted to weed out possible source problem from mozilla source code and thunderbird mail client code by using -Werror with due caution.) Thank you again for the confirmation of the fix in GCC-12.
