// g++ version: 2.95.2
// system: linux kernel 2.2.5-15smp, redhat release 6.0
// problem description:
//   has fatal error during compilation
//   when following flags are used:  -funroll-loops -O 
//   I get following error messages:
//    /tmp/ccOE5xnp.s: Assembler messages:
//    /tmp/ccOE5xnp.s:49: Error: Symbol .LEHB26 already defined.
//    /tmp/ccOE5xnp.s:57: Error: Symbol .LEHE26 already defined.
//
// note: bug goes away if non-inline destructor is  used for class X
//       or if following
//            delete[] u;
//       is removed from body of destructor
class X {
  public:
#if 1
    // doesn't work with following inline destructor
    // (works fine if delete[] u; is removed from body)
    ~X() { delete [] u; }
#else
    // also works fine with following
    ~X();
#endif
