            Bug ID: 20520
           Summary: std::list<>::remove_if() visits elements multiple
           Product: libc++
           Version: 3.4
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

When calling std::list<>::remove_if() with a lambda for the condition (I did
not test without lambdas), it visits the list entry *following* a delete twice.

Demo code and a patch can be found with the respective FreeBSD bug report:
