Description franz.sirl-kernel 2002-05-01 11:26:00 UTC 
Current CVS shows these regressions on powerpc-linux-gnu since sometime yesterday:

FAIL: 21_strings/inserters_extractors.cc execution test
FAIL: 26_numerics/complex_inserters_extractors.cc execution test
FAIL: 27_io/istream_extractor_arith.cc execution test
FAIL: 27_io/istream_sentry.cc execution test
FAIL: 27_io/istringstream_members.cc execution test
FAIL: 27_io/ostream_inserter_arith.cc execution test
FAIL: 27_io/stringstream_members.cc execution test

It is also reproducible on x86-linux-gnu if you bootstrap with:

	make bootstrap CFLAGS="-g -O2 -funsigned-char" CXXFLAGS="-g -O2 -funsigned-char" BOOT_CFLAGS="-g -O2 -funsigned-char"

On x86-linux-gnu one testcase only fails if you only run the libstdc++ testsuite with -funsigned-char

FAIL: 24_iterators/istreambuf_iterator.cc execution test

Release:
current 3.1 CVS

Environment:
glibc-2.2.5
binutils-2.12.90.0.7
