I am tring to compile a java source file into an object. The java source
file extends the IOException class but when I try to compile I get this
error message and a core file: 
gcj: Internal compiler error: program jc1 got fatal signal 11
I jave tried to compile the source file these three ways:
gcj -fPIC -shared -o MissingDataException.o -c MissingDataException.java
g++ -c -w -o MissingDataException.o MissingDataException.java
gcj -o MissingDataException.o -c MissingDataException.java
any help would be great
cheers
