Attached are patches against head to fix the reported problem + another
one I discovered during testing:
iconv-void-ptr-ptr.patch
...fixes the reported segfault, however HZ conversion still doesn't work.
iconv-HZ-start-comes-before-end.patch
...makes HZ conversion work. Verified using libiconv HZ test file.
iconv-VIQR-boundary-check.patch
...fixes a missing boundary check crash in VIQR codeset conversion
module I've discovered.
cheers,
manuel
