Please find attached a sample program, which does not compile.
Unfortunately this program depends on boost. I use the current boost version
1.33.1. The include files "algorithm" and "iostream" are the ones belonging to
gcc-4.1.1.

Can you provide the preprocessed source which you can get via -save-temps and
it will be called something .ii.
Also you can provide the error message you get?

Remark to test.cpp:23:
std::cout << boost::lambda::_1 << '\n'
This should find the overloaded operator<< defined in boost/tuple_io.hpp.

------- Comment #11 from rguenth at gcc dot gnu dot org 2006-10-27 11:04 -------
I believe the testcase is invalid. EDG says:
test.cpp(5824): error: no instance of overloaded function
"boost::lambda::lambda_functor<T>::operator() [with
T=boost::lambda::placeholder<1>]" matches the argument list
argument types are: (std::pair<int, int>)
object type is: boost::lambda::placeholder1_type
std::cout << (boost::lambda::_1)(std::make_pair(a, b)) << std::endl;

(In reply to comment #11)
> I believe the testcase is invalid.
You're right, therefore I'm closing this bug. The author of the Boost.Lambda
library, Jaakko Järvi, kindly pointed my to a section of the library
documentation, where it is written that arguments to lambda functions can't be
non-const rvalues[1].
The following patch corrects the test case:
--- test2.cpp.~1~ 2006-10-27 11:02:14.000000000 +0200
+++ test2.cpp 2006-10-30 18:05:06.000000000 +0100
@@ -11,6 +11,8 @@
int main()
{
int a = 1, b = 2;
- std::cout << (boost::lambda::_1)(std::make_pair(a, b)) << std::endl;
+ std::cout
+ << (boost::lambda::_1)(boost::lambda::make_const(std::make_pair(a,
b)))
+ << std::endl;
return 0;
}
I don't know why it compiles cleanly on VC++, though.
Best regards
Christian

However, my initial testcase (attachment #12493) does still not compile, so it
seems I have simplified it wrongly. I will check this back and reopen the bug
accordingly.
