Hi!

Consider this example: https://godbolt.org/z/MTsq91oE3

The goal is for the foo and bar functions to be SFINAE'd out under the same condition. bar() and foo() are always enabled or disabled together. bar calls foo only when both bar and foo are enabled.

However Clang complains that bar() is calling the delete'd overload foo, which should not happen as per above. GCC, EDG and MSVC do not error and compile just fine.

So I wonder if this is a bug in Clang, or are GCC, EDG and MSVC being less restrictive?

Thank you!
