$ cat impl.cc
struct A {};
template<typename T> struct t { t(); };
template<typename T> t<T>::t() {}
int main()
{
    t<A> *foo = new t<A>;
    return 0;
}

$ g++ -c -frepo impl.cc

$ c++filt <impl.rpo
M impl.cc
D /home/users/pluto/rpm/BUILD
A '-c' '-frepo' '-mtune=k8' '-frandom-seed=0x5e164bdf'
O t<A>::t()
O t<A>::t()

$ g++ -frepo impl.o -o impl
impl.o: In function `main':impl.cc:(.text+0x1c):
undefined reference to `t<A>::t()'
collect2: ld returned 1 exit status

it looks like a regression (it was fixed in 2.95.x, see PR454).

c++filt < t.rpo gives:
M t.cc
D /home/pinskia
A '-c' '-frepo' '-mtune=k8' '-frandom-seed=0x5f283832'
C t<A>::t()
O t<A>::t()

What exact version are you trying with and does it have any modifications?

It works with "4.0.3 20051105" and "4.2.0 20060208".
And I don't have any modifications to my 4.1.0 or 4.0.3, they are built clean
too.

Can you try a clean build and also do building of imp.cc in a clean directory?

And it works with "4.2.0 20060211" on powerpc-darwin.  (the other ones were on
x86_64-linux-gnu).

I should note that PR 24996 was fixed a different way then the orginal patch
was for so it might be that one.

But closing this bug as works for me as it does.

blah, g++ doesn't work. xgcc does.

[obj-x86_64-pld-linux/gcc]$ ./g++ -B. -c -frepo impl.cc

[obj-x86_64-pld-linux/gcc]$ ./xgcc -B. -c -frepo impl.cc
[obj-x86_64-pld-linux/gcc]$ ./xgcc -B. -frepo impl.o -o impl

g++ doesn't recompile impl.cc.

on 3.4.5 g++ also fails (but xgcc works).
Andrew, What you've checked in #c5, #c6 nad #c7 ?
