>Description:
	When compiling a Java source file that consists only of comments,
	gcj gets a segmentation fault.
>How-To-Repeat:
	Make a java source file with one or more lines of comments:
		// This is a comment in myfile.java
		/* This is also
			a comment */
	When you compile it, e.g.,:
		gcj -c -g myfile.java
	gcj will seg fault.
>Fix:
	Workaround:
	Don't include the file in one's compilation.  However, a big
	system might want to be configured in such a away
	that results in source files ending up having all
	comments.  It's convenient at times to comment out an
	entire file when developing.
