Architecture: i686

>Description:
The += operator for string arrays does not work.
It works for strings.
s[0] = s[0] + string works, too, though this should be equivalent to s[0] += string
This error report is meant to replace the report
java/2008: ICE in gcj (no optimization),
because it is a much simpler testcase.
Sorry, i don't know how to do that myself.
>How-To-Repeat:
cat buggy.java
public class buggy
{
public static void main(String[] args)
{
String s[] = new String[1];
s[0] = "";
s[0] += "";
}
}
gcj -c buggy.java
buggy.java: In class `buggy':
buggy.java: In method `buggy.main(java.lang.String[])':
buggy.java:8: Internal error: Segmentation fault
Please submit a full bug report, with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.
>Fix:
Workaround: Use s[0] = s[0] + "" instead of s[0] += ""
