--- Comment #2 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
When I look at tree.h:3346, I do not understand why the
operand check failed. From the message it appears that
__i==2 and TREE_OPERAND_LENGTH (__u)==4:
inline tree *
tree_operand_check (tree __t, int __i,
const char *__f, int __l, const char *__g)
{
const_tree __u = EXPR_CHECK (__t);
if (__i < 0 || __i >= TREE_OPERAND_LENGTH (__u))
tree_operand_check_failed (__i, __u, __f, __l, __g);
return &CONST_CAST_TREE (__u)->exp.operands[__i];
}
Could it be, that this is not a fortran bug but a C++ compiler bug?
