           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

Users complain that in GNU ++ very strange incredible errors appear in the
game. Which are not in the ICC compilers.

How to find code that can work in ICC with other result than in GNU ++?
(undefined behaviour?)

Any static analyzer can found this problems?
