This is easier to reproduce with mono-sgen, where it causes a crash in 
mono_sgen_los_iterate_live_block_ranges () because one of the object headers is
corrupted.

This seems to be caused by a buffer overflow in
I18N.CJK.ISO2022JPEncoder:GetBytesImpl (). Probably all the encoders need to be
reviewed and changed to use non-unsafe code.
