Andrew,
   Actually the nature of the testsuite will mask this failure on intel darwin.
The gcj compiler doesn't segfault when presented with a *.class file to compile
into an executable. Only when presented a *.java file will the gcj compiler abort.
The output to libjava.log suggests that all of the tests in libjava.lang are executed
via the class file contained in the associated jar file rather than compiling directly
the java file itself.

I suspect if the libjava harness was fixed to compile the java files if a ecj1 was
built that all of the libjava.lang tests would suddenly fail on darwin.
