On Linux/x86_64,
a01462ae8bafa86e7df47a252917ba6899d587cf is the first bad commit

libstdc++: Fix std::format output of %C for negative years
caused
FAIL: std/time/year/io.cc -std=gnu++20 execution test
FAIL: std/time/year/io.cc -std=gnu++26 execution test
with GCC configured with
../../gcc/configure --prefix=/export/users/haochenj/src/gcc-bisect/master/master/r14-6468/usr --enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --with-fpmath=sse --enable-languages=c,c++,fortran --enable-cet --without-isl --enable-libmpx x86_64-linux --disable-bootstrap
To reproduce:
$ cd {build_dir}/x86_64-linux/libstdc++-v3/testsuite && make check RUNTESTFLAGS="conformance.exp=std/time/year/io.cc --target_board='unix{-m32}'"
$ cd {build_dir}/x86_64-linux/libstdc++-v3/testsuite && make check RUNTESTFLAGS="conformance.exp=std/time/year/io.cc --target_board='unix{-m32\ -march=cascadelake}'"
$ cd {build_dir}/x86_64-linux/libstdc++-v3/testsuite && make check RUNTESTFLAGS="conformance.exp=std/time/year/io.cc --target_board='unix{-m64}'"
$ cd {build_dir}/x86_64-linux/libstdc++-v3/testsuite && make check RUNTESTFLAGS="conformance.exp=std/time/year/io.cc --target_board='unix{-m64\ -march=cascadelake}'"
(Please do not reply to this email, for question about this report, contact me at haochen dot jiang at intel.com.)
(If you met problems with cascadelake related, disabling AVX512F in command line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
