A GCC checked out from CVS on 2005-01-03 gets a segmentation fault
when compiling the following code. Jikes compiles it all right,
generating an <init> method that takes references to both First and
Second as parameters. Kaffe attempts the same but fails verification.
class First {
class Inner {}
};
class Second {
void fn(First first) {
first.new Inner() {
void crash() {}
};
}
}
$ gcj -v -C AnonExt.java

AnonExt.java:10: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
If I remove the crash() function, then GCC succeeds in compiling the
source. I haven't checked the resulting bytecode, though.
