seg fault

Sun May 26 06:53:00 GMT 2002

I've started a new project (the imap provider for ClasspathX
javamail) and I thought I'd try to do the whole thing, from the
ground up, with GCJ.
I've just built the CVS GCJ and I'm having a problem compiling even
a simple "hello world" class to native code.
Well, I can compile it, but when I run it I get a seg fault.
I'm compiling it like this:
 gcj --main=Test Test.java
I'm sure that the HEAD of the CVS is supposed to be working... but it
clearly isn't for me. It's almost bound to be something I've done,
but I'm not sure how to find out what is causing a seg fault.
Can anyone drop me a few tips for stuff that I might do to debug this
problem?
