If the extern declaration is moved to the global scope the inline substitution works correctly. The generated code creates link errors later on. g++ b.C /var/tmp/ccaFlZr0.o: In function `main': /var/tmp/ccaFlZr0.o(.text+0x8): undefined reference to `OHashKey(X const&)' collect2: ld returned 1 exit status >How-To-Repeat: class X { public: int i; }; inline const int& OHashKey(const X& x) { return x.i; } int main() { extern const int& OHashKey(const X& x); X x; return OHashKey(x); } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
