The instantiations definitely should be in libstdc++-v3/src/c++11/regex.cc in
the GCC 4.7 release branch.

I do not see the extraneous symbols using the example in comment #22 when
compiling with trunk. Also, the example G++ invocation does not enable any

I have reduced a real live case. But still using vector.
$ cat t.cc
#include vector
struct ClassicUpdate
{
ClassicUpdate();
};

Maybe the regex code is non-functional, but *something* is referencing the
symbol under certain circumstances.
I figure this

See also bug 53713. Hasn't been marked as a dup yet.

Whether or not it's more correct, the regex code is non-functional and so
needing to add symbols to the .so to support broken code noone uses or can use

Another feature of AIX is its garbage-collecting linker. The very first
implementation of GCC for AIX was forced to emit an extra symbol to tie the
text

Strangely, someone else is reporting a runtime error with the same symbol:

OK, I'll deal with it asap. I have quite a queue of patches to test and commit
at present though.

David, thank you for commenting; I have a better appreciation now of how AIX is
a different animal from most, and indeed may be doing things more correctly

We know the instantiations that are needed, but I don't want to define them for
all platforms if they're not needed elsewhere. I also have no way of testing

we might need an explicit instantiation of that type in libstdc++.so, I'll
