           Summary: ICE on incorrect parameter to @synchronized()
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: objc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: nicola@gcc.gnu.org


Here is a testcase that crashes GCC 4.6 --

typedef struct { float x; float y; } point;

int test (id object)
{
  point x;
  @synchronized (x)
    {
      return 1;
    }
}

The compiler is not checking the type of the argument of @synchronized() and is
not dealing with unexpected types correctly.

Thanks
