["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following valid code snippet triggers an ICE since GCC 4.3.0
when compiled with "-fmudflap -O":

=========================================
_Decimal128 foo(int n, ...)
{ 
  int i;
  _Decimal128 j;
  __builtin_va_list va;
  __builtin_va_start(va,n);
  for (i = 0; i < n; i++)
    j += __builtin_va_arg(va,_Decimal128);
  __builtin_va_end(va);
  return j;
}
=========================================

bug.c: In function 'foo':
bug.c:2: error: invalid operand to binary operator
