Declarations referenced in a dependent template argument may get removed

Example: http://ideone.com/QaLeKP

If I rewrite the function in the following way, everything works:
template <class Y> void f(Y& y) { typename Y::value_type value = 42; y.value = value; }

This issue is actually very important for template metaprogramming. The following example fails on multiple levels: https://ideone.com/8UCOkK

Any update on this?

No, but I'll try to look into it and see if things changed with recent clang.
Do you have your own example? Things might be subtly different, so it's good to have as many test cases as possible.

[slycelote]

ok, at least simple cases should work now.
Let me know if there's some specific scenario that is still failing for you.

Hi, @slycelote. This case fails https://pastebin.com/ipEMpeLC.

That's an unrelated problem; support for concepts is new and I expect you'll find more issues. I fixed this one.

[jcg9129]

Hi, @slycelote. Those three still fail: https://pastebin.com/W2yDdMFJ, https://pastebin.com/eFiqanZg and https://pastebin.com/ir6ACLAC. Only the last two use concepts.

The first one (without requires clause) works for me. Can you confirm you're synced to the latest commit? Also, what clang version are you using?

You are right. I was building with an old version. The first code works for me now. I am using this Docker file to build the app https://pastebin.com/Mn3K8ERg.
