--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
The code example has undefined behaviour and moving your specialization to the
top is required to make it work. You hit [temp.dep.candidate] p1:

"For a function call where the postfix-expression is a dependent name, the
candidate functions are found using
the usual lookup rules (3.4.1, 3.4.2) except that:
— For the part of the lookup using unqualified name lookup (3.4.1), only
function declarations from the template definition context are found.
[..]

If the call would be ill-formed or would find a better match had the lookup
within the associated namespaces considered all the function declarations with
external linkage introduced in those namespaces in all translation units, not
just considering those declarations found in the template definition and
template
instantiation contexts, then the program has undefined behavior."

--- Comment #2 from 1zeeky at gmail dot com ---
I am aware that the code is invalid; I'm not saying there shouldn't be an
error.

The problem is, that g++ does not stop printing the error and needs to be
killed to stop. At least mine doesn't, maybe my downstream g++, or some
component (library) it uses, is broken somehow.

Then I was mislead by your comment: "I'm not 100% sure the attached testcase
*should* compile.". I agree that the diagnostics could be improved.

Ah, sorry. I wrote that before I found out that this was the issue with the
code.

Fixed in GCC 6.2.0 and GCC 7.  In GCC 5.x and GCC 6.1.0, GCC would ICE:
'
Internal compiler error: Error reporting routines re-entered.
mmap: Invalid argument
Please submit a full bug report,
with preprocessed source if appropriate.
