This problem occurs not only with SHIFT_JIS but also with a number of
charsets.  When kaffe dumps core, the following message is displayed:

kaffe-bin: mem/gc-incremental.c:865: gcMalloc: Assertion `fidx < nrTypes && size != 0' failed.

Test results for various charsets are as follows.

Test Program
public class IconvEmptyString {
    public static void main(String[] args) throws Exception {
        "".getBytes(args[0]);
    }
}

Shell script for running the test program
rm -f core
list=`ruby listcharset.rb libiconv/libiconv-1.8/README`
for i in $list
do
    java IconvEmptyString $i
    if [ -f core ]
    then
        rm core
        echo "$i FAIL"
    else
        echo "$i PASS"
    fi
done

where ruby listcharset.rb is a program that picks up charset
names from libiconv-1.8/README.
