------- Comment #1 from bkoz at gcc dot gnu dot org  2009-04-16 22:11 -------

I suspect this is a mis-configuration of your tester. From the most current
test results:
http://gcc.gnu.org/ml/gcc-testresults/2009-04/msg00745.html

This differs in the abi_check fail from other i686 testers, which are fine.

To know the details of why abi_check fails, you'd need to examine the generated
libstdc++.log file, and look for abi_check. There will be a bunch of symbols
either added, missing, etc.

My off-hand guess is that you are missing the gnu locale stuff. To fix,
configure with

--enable-clocale=gnu

from:
http://gcc.gnu.org/onlinedocs/libstdc++/manual/configure.html

You might want to start with configuring with known good options and trying to
replicate passing results. See these baselines:
