>Description:
gcj 3.1 generates a segmentation fault while building the xerces parser and
generating byte code. The compiler does not seg fault when compiling
to object code or just generating dependencies.

I have tracked the problem down to the initialization of
static strings with line continuation '+' characters. Folling is a
simple example that causes the seg-fault.
public class StringCrash {
static final String viramaString =
"f"
+"o"
+"o"
+"b"
+"a"
+"r";
public static void main(String[] args) {
System.out.println("viramaString= " + viramaString);
}
};

Compile the above example with the '-C' option.

workarounds:
- don't compile to byte-code
- or don't use string continuation when compiling to byte code
