 thanks: 32-bit testsuite results look reasonable again:

 64-bit testing is broken right now due to an unrelated problem; I'm still
 investigating what's going on there.

>Description:
Between 3.1 20020412 and 20020426, several libstdc++ testsuite failures
started to occur on both Solaris 8/SPARC and Intel:

+FAIL: 21_strings/inserters_extractors.cc execution test
+FAIL: 24_iterators/istream_iterator.cc execution test
+FAIL: 26_numerics/complex_inserters_extractors.cc execution test
+FAIL: 27_io/instantiations.cc execution test
+FAIL: 27_io/istream_extractor_char.cc execution test
+FAIL: 27_io/istream_extractor_other.cc execution test
+FAIL: 27_io/istream_manip.cc execution test
+FAIL: 27_io/istream_seeks.cc execution test
+FAIL: 27_io/istream_sentry.cc execution test
+FAIL: 27_io/istream_unformatted.cc execution test
+FAIL: 27_io/istringstream_members.cc execution test
+FAIL: 27_io/ostream_inserter_arith.cc execution test
+FAIL: 27_io/ostream_inserter_other.cc execution test
+FAIL: 27_io/stringstream_members.cc execution test

Those tests that existed in 3.0 passed there, so this is a regression.

Running e.g. 24_iterators/istream_iterator.cc under gdb 5.2 (after
compiling src/misc-inst.cc and test test proper with -g3 -gdwarf-2), I get
the following stack trace:

Program received signal SIGSEGV, Segmentation fault.
