Jan,
I'm curious: can you see if C++ unit-at-a-time solves this bug? If so, that
would be really excellent: this is probably a 5-10% runtime hit.
thanks,
benjamin

It is fixed with -funit-at-a-time in c++. Should we close this, now it is fixed with -funit-at-a-
time?

Oh really......... veeeeery interesting.
This may make a substantial difference in libstdc++ runtime performance. Can all
of libstdc++ and the libstdc++ testsuite be run with this flag?

Yes. You may even hack opts.c to enable unit-at-a-time at -O2 and get
practically useable compiler.
I hope I will make unit-at-a-time by default at -O2 for 3.4 but until
this happens (or in case I hit the wall somewhere) we can compile
libstdc++ with it. The resulting library is few % bigger that is quite
non-standard (usually I get code size reduction from c++ code in
unit-at-a-time). It would be nice to understand the reason.

I would guess so. Or you can assign it to me and we can wait until
-funit-at-a-time become default in case this won't take forever.

Actually the transition to -funit-at-a-time is not seamless for libstdc++.
I first re-compiled libstdc++ by using
make CXXFLAGS="-g -O2 -funit-at-a-time" all
after removing the build directory. Then, I added -funit-at-a-time to
scripts/testsuite_flags.h so that
--cxxflags)
CXXFLAGS_save="-g -O2 -funit-at-a-time"
Then, I ran make-check in the libstdc++ build directory. I got seven new failures:

These all exhibited the same pathology: missing definitions for virtual dtors.
