Bug ID: 64937 Summary: [5 Regression] compare debug failure with -fsanitize=address Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: middle-end Assignee: unassigned at gcc dot gnu.org Reporter: burnus at gcc dot gnu.org Split-off from PR64935, which shows the same message but is caused by a different revision. The attached test case fails for me with GCC_COMPARE_DEBUG=yes g++ test.ii -fsanitize=address with the same message: g++: error: test.ii: -fcompare-debug failure (length) Test case is attachment 34664 Works with current 4.9 branch, fails with today's trunk and also with r220315 (the other PR, PR64935, works with that revision).
