appeared on mainline between 20050816 and 20050817 (both at 07:00 UTC, some IRC
discussion suggests a narrower timeframe is known but I don't see an open bug
for these failures), on multiple platforms (at least i686-pc-linux-gnu,
hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11, ia64-hp-hpux11.23).

ia64-linux as well.  These tests seem to have been failing for a while on mmix.
 See pr19747.

Which might mean that libstdc++ is mis-compiled.

As reported here:
http://gcc.gnu.org/ml/gcc-regression/2005-08/msg00040.html
This is testsuite problem caused by the update of the address of the FSF.

Kelley, can you please fix the regression that you introduced? (obviously, you
didn't completely regtest the patch). I suggest first padding the new address
to the length of the old one with spaces then, in case the checked chars fall
inside the address itself, also adjust the checked values to the new ones. In
any case, please don't change the size of the file and the various integer 
constants in the testcases.
