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
<retval>
bug.c:2: internal compiler error: verify_stmts failed
