I get this failure building libstdc++:
/home/rask/build/gcc-m32c-unknown-elf/m32c-unknown-elf/m32cm/libstdc++-v3/include/ext/bitmap_allocator.h:
In member function 'void
__gnu_cxx::bitmap_allocator<_Tp>::_M_deallocate_single_object(_Tp*) [with _Tp =
wchar_t]':
/home/rask/build/gcc-m32c-unknown-elf/m32c-unknown-elf/m32cm/libstdc++-v3/include/ext/bitmap_allocator.h:1027:
internal compiler error: in smallest_mode_for_size, at stor-layout.c:220
Can be reproduced with this command line and the attached preprocessed source:
./xgcc -B./ -O2 -mcpu=m32cm ~/bitmap-allocator.cc -S -o /dev/null
These are the flags I configured gcc with:
--target m32c-unknown-elf --with-newlib --enable-sim --disable-gdb
--disable-nls --enable-languages=c,c++ --enable-cxx-flags=-O2
--
