--- Comment #4 from qinzhao at gcc dot gnu.org --- (In reply to qinzhao from comment #3) > The warning disappears after adding -fno-thread-jumps. > looks like similar issue as PR109071 further study turned out that: although using -fno-thread-jumps suppressed the warning, the situation is different than that of PR109071. the approach to improve the diagnostic for PR109071 actually didn't work here.
