Thanks.  Unfortunately, I don't know what could be causing this.
Everything looks fine, except that the compiler is crashing.  I'm not
seeing this on Solaris 11.  I think you will have to debug the
compiler.  To see more about what is happening, run the "compile:"
command by itself.  It should crash in the same way.  Then run it with
the -v option to see how the go1 program is being run.  Running the
go1 program with those arguments should crash.  That is what you need
to debug; presumably there is a NULL pointer dereference or something.
