           Summary: Runtime with an array of std::vectors
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3

The entire program

The following program crashes if compiled with -O2:

   for (int i=0; i<=1; i++)
      for (int j=0; j<=1; j++) {
         std::vector<int> a[2];
         a[i].push_back (0);
      }

If we remove any 'for' loop, or if we change a[i] to a[0] or to a[1] - there
will be no crash.
