I've confirmed that 22_locale/ctype/is/char/3.cc doesn't fail if linking with libstdc++.a which is built with the compiler without r184966 changes. The .s files against 3.cc are same with the both compilers. It looks that the problematic object is libstdc++-v3/src/c++98/ctype_configure_char.o because the error went away if replacing it with another one. I've attached .i and .s files for that file. The option used is COLLECT_GCC_OPTIONS='-shared-libgcc' '-B' '/exp/ldroot/dodes/xsh-gcc/./gcc' '-nostdinc++' '-L/exp/ldroot/dodes/xsh-gcc-orig/sh4-unknown-linux-gnu/libstdc++-v3/src' '-L/exp/ldroot/dodes/xsh-gcc-orig/sh4-unknown-linux-gnu/libstdc++-v3/src/.libs' '-B' '/usr/local/sh4-unknown-linux-gnu/bin/' '-B' '/usr/local/sh4-unknown-linux-gnu/lib/' '-isystem' '/usr/local/sh4-unknown-linux-gnu/include' '-isystem' '/usr/local/sh4-unknown-linux-gnu/sys-include' '-I' '/exp/ldroot/dodes/ORIG/trunk/libstdc++-v3/../libgcc' '-I' '/exp/ldroot/dodes/xsh-gcc-orig/sh4-unknown-linux-gnu/libstdc++-v3/include/sh4-unknown-linux-gnu' '-I' '/exp/ldroot/dodes/xsh-gcc-orig/sh4-unknown-linux-gnu/libstdc++-v3/include' '-I' '/exp/ldroot/dodes/ORIG/trunk/libstdc++-v3/libsupc++' '-fno-implicit-templates' '-Wall' '-Wextra' '-Wwrite-strings' '-Wcast-qual' '-Wabi' '-fdiagnostics-show-location=once' '-ffunction-sections' '-fdata-sections' '-frandom-seed=ctype_configure_char.lo' '-g' '-O2' '-D' '_GNU_SOURCE' '-S' '-fPIC' '-D' 'PIC' '-o'
