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
