Trying this patch with an arm-elf-linux target, I find the build fails in libstdc++:

../../../../libstdc++-v3/src/codecvt.cc -o codecvt.o
/home/nick/riscos-elf/gcc-4.1/arm-elf-riscos/arm-elf-riscos/libstdc++- v3/include/bits/locale_facets.h:676: internal compiler error: Segmentation fault


I noticed that too but only with a compiler built at -O2 showed it.

The testcase I found which produced that error with a compiler built at -O2 is:
struct facet { virtual ~facet(); };
struct ctype_base {};
struct ctype : facet, ctype_base {};


So maybe there is a miscompiling with my base compiler I don't know.
or there's an uninitialized var

could you send me the codecvt.ii file? I'll see if I can reproduce it with a cross compiler.
