I get the following gcc 4.2 regression:

11031:tbm@deprecation: ~] /usr/lib/gcc-snapshot/bin/g++ -c -O2
mysql-sp_cache.cc
mysql-sp_cache.cc: In function 'void sp_cache_invalidate()':
mysql-sp_cache.cc:20: internal compiler error: in add_virtual_operand, at
tree-ssa-operands.c:1309

    volatile int counter;
  }
  atomic_t;
  static __inline__ void atomic_inc (atomic_t * v)
  {
    __asm__ __volatile__ ("lock ; "
                          "incl %0":"=m" (v->counter):"m" (v->counter));
  }
}
static ulong volatile Cversion = 0;
void
sp_cache_invalidate ()
{
  atomic_inc ((atomic_t *) & Cversion);
}
