I think this was fixed by the patch for 69515.  In any case, it works now.

--- Comment #2 from Tom Honermann  ---
The change in comment 1 introduced a regression.  The following test passes
with r234230, but fails with r234231:

$ cat t.cpp
template 
constexpr bool b = false;
template
constexpr bool b = true;
int main() {
b;
b;
}

$ g++ -std=c++14 t.cpp -o t
/tmp/ccJTAQId.s: Assembler messages:
/tmp/ccJTAQId.s:27: Error: symbol `_ZL1b' is already defined
