Comment 15 for bug 75724

Created attachment 13815
Test case fixed using forward declarations

Thank you for your help. I think I now have a better understanding of what is going on. As far as GCC is concerned the overriding visit_each template function dealing with MyData does not exist when it makes its decision regarding visit_each(v, data, 0); call.

I am attaching fixed (working with 4.1) text case that is more representative of the boost structure (to the best of my understanding). Also, I will be using it as a base for a follow up issue I ran into.

I am also including couple of relevant links for better context to this issue for anyone else who might stumble on this entry:

Two Phase looks ups and GCC:

http://gcc.gnu.org/onlinedocs/gcc/Name-lookup.html

IMHO, the changes are mentioned as early as gcc 3.4 but they did not seem to fully kick in until gcc 4.x.

Related boost email and change that I found:
