The problem starts with the fact that there's no definition of iconv_t in
place, since iconv.h isn't included anywhere.  I haven't yet found where in
the maze of libstdc++ headers to add this.  One plausible location seemed
to be config/locale/generic/c_locale.h, but this didn't help.

Apart from that, there shouldn't be an ICE here.

Even if I add <iconv.h> directly to extc++.h (a complete hack), the
compilation errors about iconv_t missing are gone, but the ICE remains,
even at -O0.

Can you give the .ii for that?

On x86-linux-gnu with FC4 I hear, I could not reproduce it on FC5,  I am in the middle

The ICE is a duplicate, but the compile failure before is not (though it could
be
the same issue as libstdc++/28265).

------- Comment #12 from pcarlini at suse dot de  2006-07-09 17:39 -------
It seemd to me that the best thing to do is adding the include on top of
codecvt_specializations.h itself and removing it from the other places where it
does currently appear (because a grep reveals that the iconv facilities are
*not* used anywhere else (besides the testsuite), I would appreciate of you
could double check...). Can you try that?

Forgot: those facilities are not always available, therefore we should probably
protect the whole thing with _GLIBCXX_USE_ICONV... I'm adding Benjamin in CC.

The compilation errors are gone with this change, but due to PR c++/28217,
I still get an ICE:
